Use of Fluorinated PBDE’s as Aides in the Identification of Native PBDE Congeners

Polybrominated diphenyl ethers are a group of brominated flame retardants used primarily as additives in various plastics and polymers. Due to their widespread use as well as their tendency to leach from the polymer matrices, PBDEs have become a major class of environmental pollutants. The ability to bio-accumulate and the structural similarities to PCBs have led to concern over the possible health effects of PBDE exposure.

Chillers & Baths

Instrument noise, particularly from cooling devices, can take its toll on laboratory workers. Noise interferes with conversations but can also induce stress, leading to irritability, anxiety, and poor performance. Lab workers are particularly susceptible, as decibels in busy labs can add up quickly from refrigerators, freezers, aspirators, fume hoods, and chillers. Noise is therefore an important factor when choosing a chiller.

Lab Furniture

Taking some time to investigate the lab’s operations to uncover inefficiencies is a key part of successful lab design. It’s important to note any complaints regarding lab ergonomics: benches that are too high or crowded, not enough space for computer-related work, workflows scattered around the lab instead of being concentrated.

Glove Boxes

A glove box consists of a sealed box with the inside accessible only by gloves. Though their uses are expanding, they are essentially utilized for two basic purposes: Protect what you work on from the environment, such as an analytic balance on a production floor, or protect you from what you work on, such as a virus. Despite the fact that most glove boxes provide a relatively simple process, different applications require different boxes.

Homogenizers

Turning a sample into a suspension—the essence of homogenizing—occurs in a wide range of laboratory applications. In life science and clinical research, scientists often homogenize tissue samples for various analytical studies.

LIMS

Mobile technology is finally picking up steam in laboratory information markets. The sweet spots for mobile access are sample collections occurring outside the lab, for example, taking health and safety samples throughout a pharmaceutical facility, in collecting environmental samples in the field, or when testing labs become too cramped to house stand-alone data systems and hardware. On one hand developers of mobile applications strive to be platform-agnostic, but many are now developing dedicated “apps” as well.

Chromatography Data Systems

Chromatography data systems (CDSs)— the data “back end” for gas, liquid, ion, and supercritical fluid analytic chromatography—have evolved over the decades from simple chart recorders to onboard processors with minimal storage and analysis to personal computer-based and, finally, to connectivity with “peer” instruments and supervisory software systems. Today’s CDS is multifunctional, multitasking, and often vendor-neutral.

Electronic Laboratory Notebooks (ELNs)

Collaborative research is one of the justifications cited most often for acquiring lab data software. A good case can be made for upgrading a LIMS or ELN based solely on the software’s age and there are many other reasons to upgrade or replace a LIMS or ELN. Rarely, workflows or instrument configurations change such that the old system is rendered obsolete. More frequently, the user is interested in adding some capability that is not presentfor example, notebook-like functionality to a LIMS or sample tracking within an ELN.

Top 6 Questions You Should Ask When Buying an Optical Microscope

Mills & Grinders

To grind something solid, many of us might think of a mortar and pestle as the original grinding machine. In fact, that technology goes back at least to 1550 BCE, when one was described in Egyptian writing. Many other hand-powered mills and grinders followed, leading to powered devices in today’s many forms.

pH Meters

An old analog pH meter seemed accurate enough, as long as the task didn’t require much accuracy. Today’s meters must be more accurate and provide more reproducible results. In some cases, pH meters do even more. Some customers want multifunction meters—a device might measure various parameters, including pH, conductivity, ion concentration, and oxidation reduction potential.

Power Supplies

Since standard laboratory equipment contains its own individually-designed power supplies that plug into standard electrical outlets, many labs rarely use external power supplies—mostly for specialty applications, instrument testing, and design. OEM power supplies operate steadily and predictably at one output inside equipment, instruments, and computers. By contrast, low- and medium-voltage programmable supplies are designed for applications—particularly in testing, measurement, and instrument design— where users might require 12V one day and 5V the next.

2014 Product Resource Guide: Refractometers

Refractometers come in all sizes, shapes, capabilities, and prices. Some readers may recognize refractometry as a “high school” analysis method or a specialized technique for measuring specific analytes like sugar in water. Increasingly, lab and process engineers employ refractometry to provide quick measures of key quality attributes that under normal circumstances would require much lengthier assays on significantly more expensive equipment.

2013/2014 Product Resource Guide: Shakers

Assays from academics to industry require shakers. In the life sciences, for example, one expert says the new uses of shakers basically mimic what you see in the industry, which is an increase in the use of genomics. He adds shakers are used in almost every application in some fashion. For example, shakers are widely used in cell culture work.

FTIR Spectrophotometers

Fourier transform infrared (FTIR) spectroscopy, a subset of infrared (IR) spectroscopy, uses a mathematical algorithm, Fourier transform, to translate raw infrared data into a spectrum. FTIR is useful for the analysis of organic and inorganic compounds that exhibit changes in polarity as a result of the vibration, spinning, or perturbation of molecular bonds. FTIR methods are common in such industries as foods, materials, chemicals, pharmaceuticals, forensics, and others. Advantages of FTIR over conventional IR are higher resolution, better signal-to-noise, easier analysis of very small samples and poorly-absorbing species, and much more rapid analysis.

Atomic Absorption Spectrophotometers

Atomic absorption (AA) has been known since the 19th century, but it was not until the 1950s, thanks to efforts by Alan Walsh at Australia’s CSIRO research center, that use of AA spectrometers became routine for metals analysis.

UV-VIS Spectrophotometers

Ultraviolet-visible (UV-Vis) spectrophotometry is arguably the most common as well as one of the oldest forms of absorption-based analysis. UV and visible regions of the electromagnetic spectrum are contiguous: UV wavelengths range from 10 to 4000 angstroms; they are visible from 4000 to 7000 angstroms.

Thermal Analyzers

Thermal analysis is the broad category of at least 20 techniques that measure some fundamental property of matter as a result of adding heat. For example, dilatometry measures volume changes upon heating, thermomechanical analysis quantifies the change in dimension of a sample as a function of temperature, and thermo-optical analysis detects changes in optical properties on heating or cooling.

2013 Guide to Purchasing a Titrator

While titration is a basic analytical method, titrators are specialized instruments that perform titrations with minimal operator intervention. They can thus minimize errors, improve throughput, and facilitate documentation. There are two major titrator types: potentiometric acid-based designs and Karl Fischer titrators.

TOC Analyzers

A mainstay of environmental and quality control chemistry, TOC analyzers measure the carbon content of dissolved and particulate organic materials in water. The carbon measured may arise from any combination of living or dead organisms and chemical contamination. TOC often serves as a surrogate for more difficult measurements, for example, contamination from petrochemicals, solvents, pharmaceuticals, chlorinated industrial chemicals and pesticides. It can also act as a screen for additional analysis.

Vacuum Pumps: Considerations for Purchase and Servicing

Vacuum pumps are an essential piece of equipment and are used in a wide variety of processes in most laboratories. Over the past 25 years, vendors have made significant innovative improvements to vacuum pumps, with important developments in high vacuum technology, corrosion resistance, vacuum control, and improvements in the efficiency and ecological impact of vacuum pumps.

Viscometers

Many industries measure viscosity, though the biggest user is the quality control department using single-point measurement. Research scientists also use viscometers to see how a material reacts to being sheared. The task at hand determines the kind of viscometer to use— different viscometers measure different magnitudes of viscosity and different changes in it. According to one expert, the most important factor to consider when buying a viscometer is robustness, even if users have to give up some sensitivity.

Water Purification Systems

Lab workers tend to treat water systems like utility or house water—open the spout and pour it out. That is partly true, as water systems have become ultra-reliable. What scientists often fail to note is how thoroughly lab operations depend on water quality. There may be some leeway in certain operations, such as cleaning glassware that will wind up in an autoclave, but even there, delicate techniques such as atomic absorption and polymerase chain reaction are extremely sensitive to impurities.
