Technology
Despite the vigilance of federal, state and local regulators and of accreditation organizations that evaluate and certify laboratories, the development and maintenance of quality in laboratories are constant concerns.
Leadership and Staffing
A change in behavior, in attitude or in lifestyle is not easy to achieve, and some seem near impossible. However, the change process can be understood, and change can be implemented more successfully and more reliably by following a few rules.

The Politics of Stem Cell Research
The NIH recently published its annual report on funding levels for various research, condition, and disease categories. Since the NIH is a government institution, it should come as no surprise that the biggest changes came in areas that have been th
Managing the Coming Data Flood
Lab managers will face an increasing challenge in the next decademanaging a rising tide of data. To realize the full benefit and value of these diverse and voluminous data requires effective data management techniques, institutional arrangements, an
A new 12-year-rated UPS battery has a smaller carbon footprint but, equally important, will be ready to supply clean power when instruments and other automated test equipment are exposed to utility power problems.

AA Spectroscopy: Sensitive, Quantitative Metal Analysis
Atomic absorption (AA) has been known since the 19th century, but it was not until the 1950s, thanks to efforts by Alan Walsh at Australias CSIRO research center, that use of AA spectrometers became routine for metals analysis.
Raman Spectroscopy: Stepchild of Vibrational Spectroscopy Comes of Age
Raman spectroscopy is based on the interaction of visible, near-infrared, or near-ultraviolet light on chemical bonds. When excited with light energy, bonds experience short-lived, higher-energy vibrational states.

FTIR Spectroscopy: Picking up Steam in Nontraditional Markets
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.
Chromatography-Mass Spectrometry: Best of Both Worlds
Among the hyphenated mass spectrometry (MS) techniques, gas chromatography-MS (GC-MS) and high-performance liquid chromatography- MS (LC-MS) are the most notable. These methods combine the resolving power of high-resolution chromatography
UV-VIS Spectroscopy: It's all in the Chromophores
Ultraviolet-visible spectroscopy (UVVis), an absorbance-based analytical technique, measures and identifies chemicals that absorb in the contiguous ultraviolet and visible regions of the electromagnetic spectrum. UV wavelengths range

Management
One of the best approaches for proactively managing obsolescence is to develop and maintain a multiyear capital plan that explicitly designates a specific portion for instrument replacement each year.
Multi-vendor service models continue to evolve in order to address changing customer and market needs, such as the increasing need for asset utilization data that is vendor independent.

How It Works
Consistent, Stable Incubator and Oven Temperature
Problem: Many experienced lab technicians are aware of the sweet spot in their oven or incubatorthe back right-hand corner of the middle shelf where their experiment or process always comes out right.
Sample Prep for Phospholipid Removal
Problem: Excessive background from endogenous sample matrix components has always been of great concern in bioanalysis, and has become paramount today with the need for decreasing analytical run times. In bio-analytical mass spectrometry, the issue
Measuring Sample Volume and Detecting Precipitates
Problem: Significant time and effort is expended in screening chemical and biological sample libraries. However, no matter how advanced the screening system, the end results are only as good as the quality of the sample in the microplate wells.
Accurate Shearing of Chromosomal DNA
Problem: All contemporary, as well as NextGen and Third Generation sequencing methodologies are dependent on the generation of DNA fragments from initial MegaBase long chromosomal DNA molecules. General requirements are that such fragments have to
