Acetonitrile is the most commonly used organic mobile phase component due to its unique properties that set it apart from the other LC solvents (midrange solvent strength, excellent solvent performance, generation of well-defined chromatographic peaks, and lower viscosity and lower UV cutoff compared to alcohols and ethers). Acetonitrile is typically a by-product of the large-scale production of acrylonitrile (from ammonia and propylene) and may contain a wide range of very low-level impurities, including acrylonitrile, a(ß)- methacrylonitrile, cis/trans butenenitrile, acetaldehyde, acetone, methanol, ethyl cyanide, acrolein, allyl alcohol, propenoic acid, oxazol, and acetic acid. Trace amounts of the above impurities may remain in HPLC acetonitrile even after a sophisticated purification process. Some of these trace impurities not only can lead to high baseline and ghost peaks, interfering with the qualification and quantification of analytes, but can also contaminate the column and block the system, resulting in malfunction of the instrument...

This year marks the 25th anniversary of inductively coupled plasma-mass spectrometry (ICP MS). The marriage of ICP and MS resulted in an analytical technique capable of multielemental determinations. This capability opened up larger areas of the periodic table for environmental, forensic, biological, and material science analysis. Since its birth, ICP-MS has evolved rapidly and is at the forefront of elemental and trace metals analysis worldwide...

Chemical warfare (CW) agents are poisons that incapacitate, injure, or kill through toxic effects on the skin, eyes, blood, respiratory system, or nervous system. The CW nerve agents1 are a class of cholinesterase-inhibiting organophosphorus compounds related to organophosphate pesticides, but having a much higher mammalian acute toxicity. These agents are traditionally divided into G agents, such as tabun (military designation, GA), sarin (GB), soman (GD), or cyclosarin (GF), and V agents, such as VX. As shown in Figure 1, they are derivatives of phosphoric or phosphonic acids and contain two alkyl groups and a leaving group. While these compounds differ among themselves in certain physical properties, the toxic actions of all the nerve agents are very similar...

One of the most common laboratory activities is weighing. Whatever is being weighed, there are numerous sources of error that can sabotage the weighing and ultimately affect the quality of the final product. In order to control the risks associated with the weighing processes, good decisions are necessary. Controlling weighing accuracy can be a challenge. However, risks can be minimized and controlled with a minimum amount of effort. It is helpful to have professional guidance to make those decisions easy...

Theoretical research indicates that, with all variables controlled, Class II biosafety cabinets (BSCs) with brushless direct current (BLDC) motors can save up to 80% in energy costs over conventional cabinets with alternating current (AC) motors. To validate this theory, the University of Michigan (Ann Arbor) conducted a field study on three brands of biosafety cabinets. The study showed that the BLDC cabinets can save significant amounts of energy over conventionally powered units and that this benefit is realized over a wide range of filter loading conditions. Therefore, the energy savings available from BLDC Class II biosafety cabinets warrant earnest consideration before purchasing AC motor Class II biosafety cabinets...
