Event Overview:
Various sample extraction techniques can be used for analysis of volatile organic compounds (VOCs) in water or soil matrices. Headspace (HS) analysis is a direct and efficient method that facilitates the extraction of VOCs from a nonvolatile matrix, bypassing the need for lengthy sample preparation.
However, some manual steps are required for HS analysis. Manual preparation involves transferring the water sample into an HS vial and incorporating a matrix modifier, internal standards (ISTDs) and surrogates into a batch of samples. This process occurs prior to initiating the analytical sequence, which includes sample incubation and gas chromatography analysis. Additionally, it is necessary to prepare calibration standards, perform the appropriate dilutions, and subject them to the same procedure.
The Thermo Scientific™ TriPlus™ SMART VOC Sample Prep Station
is a dedicated autosampler designed to automate the entire process. It handles calibration standards dilution and the addition of fresh reagents to standards and samples immediately before incubation. This maintains the samples’ integrity and ensures optimal data accuracy and precision.
When coupled with the Thermo Scientific™ ISQ™ 7610 Single Quadrupole GC-MS, the system provides unattended operation and exceptional sub-ppb levels sensitivity for VOC in water samples. Thus, automating the process significantly enhances the efficiency and accuracy of VOCs analysis.

RAFA 2024 Highlights: Contemporary Food Contamination Analysis Using Chromatography
November 18th 2024A series of lectures focusing on emerging analytical techniques used to analyse food contamination took place on Wednesday 6 November 2024 at RAFA 2024 in Prague, Czech Republic. The session included new approaches for analysing per- and polyfluoroalkyl substances (PFAS), polychlorinated alkanes (PCAS), Mineral Oil Hydrocarbons (MOH), and short- and medium-chain chlorinated paraffins (SCCPs and MCCPs).
Pharmaceutical excipients, such as polyethylene glycol-based polymers, must be tested for the presence of ethylene oxide (EtO) and 1,4-dioxane as part of a safety assessment, according to USP Chapter <228>.
