Welcome again, to Day 2 of ASMS 2009. We?re pleased to bring you our continued coverage from Philadelphia, Pennsylvania. ASMS is in full swing, and last night?s hospitality suites were as crowded as ever, as you might imagine. Tonight promises to be another crowded night at the Marriott, but before then, there is a whole day of mass spectrometry-related science.

The call for increased biofuel production will surely be closely followed by a need for improved methods of analysis. The six presentations in this Tuesday morning session will examine various roles of mass spectrometry in biofuels analysis and will cover topics such as biodiesel characterization, metaproteomic analysis of termite microbes relevant to biofuel development, and multiple reaction monitoring of biofuels systems metabolic pathways.

United States Pharmacopeia (USP) general chapter 1058 on analytical instrument qualification (AIQ) has finally become official and was released in August 2008 in the first supplement to the USP XXXI.1 This column reviews AIQ and discusses the impact it will have in the regulated chromatography laboratory.

The Application Notebook
Evaporation-free extraction (no drying down) is highly desirable because of its reduced cost and pollution, higher speed, and less possibility for contamination and conversion. Presented in this article are four types of evaporation-free extraction that are widely applicable. The first one is for the determination of didanosine over the range of 25.02–2502.00 ng/mL by injecting solid-phase extraction (SPE) eluate directly. The second is for the determination of betamethasone phosphate over the range of 2.51–250.60 ng/mL by injecting SPE eluate after pH adjustment. The third is for the determination of sumatriptan over the range of 0.99–99.40 ng/mL based upon SPE with high organic washing and low organic elution. The fourth is based upon automated dilution after protein precipitation for the determination of raloxifene-4'-glucuronide and raloxifene-6-glucuronide over the ranges of 2.02–202.40 ng/mL and 0.40–39.95 ng/mL, respectively.
