With its new 875 Karl Fischer Gas Analyzer, Metrohm combines decades of experience in moisture analysis and sample handling. The KF Gas Analyzer is designed to handle nearly any gas sample – compressed, liquefied or native. It is fully equipped to measure the absolute moisture content of LPG, petrochemical intermediates, natural gas or other compressed or liquefied gases.

The aim to achieve ultrafine and nano-sized materials is becoming of great importance as effort in nanotechnology is a key driver in the development of innovative products.  To attain particles in this region, many techniques can be used such as synthesizing such materials as well as high energy milling. 

Inductively coupled plasma optical emission spectrometry (ICP-OES) is used for elemental analysis of everything from soil and sludge to water and wastewater, plus various industrial process materials. In evaluating ICP-OES instruments, environmental contract laboratories may prioritize sensitivity and speed. Industrial research laboratories may emphasize stability and analytical precision. However, both agree on the importance of controlling costs.

Refractometer manufacturers quote accuracy and reproducibility to the fourth, fifth, and sometimes even the sixth decimal places. A good manufacturer will only advertise this level of accuracy after carefully running standards.

Knowing how instruments are utilized throughout your laboratory is important information to help you optimize operations, drive cost savings and improve productivity.  However, capturing information on instrument ultilization in a lab comprised of an array of different manufacturers, techniques, control software and computer platforms presents a difficult challenge.  Until now.

Clinical laboratories have among the most stringent requirements for purity of input materials (reagents, solvents, assay kits, gases, etc.). Yet the Clinical Laboratory Improvement Amendments of 1988 (CLIA), officially promulgated in 1992, leave to clinical and diagnostic laboratory managers the task of assuring the quality and performance of chemicals and gases used to calibrate instruments and conduct general lab operations.

In my days in the lab, a pipette seemed about as impersonal as a lab tool could get. Today’s world of scientific equipment offers many ways to personalize your pipetting. For old-school scientists like me, though, the first question is: why personalize a pipette?

Many labs use chillers to control the cooling needed for some processes. To make the device work, a chiller uses a fluid, and the best kind of fluid depends on a range of factors. Part of the selection process depends on lab preferences. This article explores some of the thinking behind picking one chiller fluid over another.

The first question facing lab managers looking for an incubator is whether a dry or humidified incubator will serve their needs. Both designs have their pluses and minuses. Humidified CO2 incubators provide tighter control over cell culture conditions such as temperature, gas mix, and of course humidity.

Portable gas chromatography (pGC) is all about tradeoffs. Users demand value, reliability, ease of use, ergonomics, and measurement quality but with analysis limited to gases.

Most food producers are subject to a broad range of regulations and standards, from industry-wide ones such as ISO 22000 (which sets out several communications and system management guidelines), the United States Food Safety Modernization Act (FSMA) of 2011 and the European Union Regulation (EC) No. 178/2002 to process-specific ones like the Egg Products Inspection Act (EPIA) or the Federal Meat Inspection Act (FMIA).

Protecting your life’s work with a proper monitoring system has become increasingly important in research. A study conducted by Stanford University revealed that more than $2 billion worth of samples were stored within their freezers. Furthermore, many biorepositories and biobanks have hundreds of freezers storing priceless samples.
