Gerstel GmbH & Co. KG celebrated its 50th anniversary this year and to mark the occasion hosted a gala event open to its staff and partners from across the globe.

I hear the words “struggling for sensitivity” so often when speaking to folks using LC–MS for bioanalysis, environmental analysis, metabolomics, proteomics, and a host of other applications where target analytes are present at low concentrations in complex matrices. We spend fortunes on MS/MS instruments to increase specificity of detection in order to improve sensitivity. Some of us go to great lengths to optimize sample extraction and HPLC conditions in order to minimize matrix suppression effects and improve specificity and hence sensitivity.

Fast gas chromatography (GC) has received new attention recently in the form of available enhanced instrument capabilities. This instalment reviews important characteristics and requirements of fast GC: What can fast GC do for separations, and how can laboratories take advantage of enhanced separation speeds?

Incremental sampling methodology laboratory processing is used to produce an appropriately sized subsample that has the analytes of interest at the same concentration as the large incremental sample collected in the field. The end goal is to produce results that represent the conditions at the site and facilitate good decisions.

Looking back, there are a great many names immortalized across all fields of science and technology, which we first hear about in the undergraduate lecture halls, and perhaps only later learn to truly appreciate as the innovators and inventors of an impactful technology that has lasted the test of time. A couple of names that at present are probably not yet commonplace in the undergraduate science class are those of Hideo Kodama and Chuck Hull.

Perhaps the largest source of error with sampling and sample preparation, especially with solid and semisolid samples, is the sample heterogeneity. Generally, sample heterogeneity is managed by sample homogenization, such as grinding and mixing, as well as use of an appropriately large sample size. Incremental sampling methodology (ISM) involves structured composite sampling and a processing method to create an unbiased estimate of the mean concentration of soil contaminants. Hence, ISM is emerging as a preferred methodology for conducting field environmental sampling. In this month’s instalment of “Sample Preparation Perspectives”, we describe the application of ISM to laboratory subsampling protocols.
