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.

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

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.

The intensity of the light scattering signal depends on concentration, molar mass, and the specific refractive index increment, dn/dc, of the sample. dn/dc therefore usually needs to be known to derive molar masses by gel permeation chromatography/size-exclusion chromatography-light scattering (GPC/SEC-LS). How to overcome the issue of unknown refractive index increments is outlined in this instalment of Tips & Tricks. In particular, a new approach to derive molar masses by GPC/SEC-LS that requires only the molar mass of a reference material, and not the dn/dc of the sample or of the reference material, is introduced.

The three-day Chromatographic Society meeting was held on Monday 15th until Wednesday 17th May 2017 and was hosted by Pfizer at Discovery Park in Sandwich, Kent, UK. This comprehensive symposium featured oral presentations from leading practitioners of supercritical fluid chromatography (SFC) and ultrahigh-pressure liquid chromatography (UHPLC) from across Europe. Some of the latest innovations and applications were described and the lectures were augmented and supported by a comprehensive exhibition of instrumentation and consumables. The attendees gained insight into practical application of these techniques across a variety of industries, particularly the pharmaceutical industry. The comprehensive programme had a significant focus on SFC for chiral and preparative-scale analysis.
