Application Note 250: Correlating consumer sensory experience of apple aroma with VOC profiles acquired by automated TD–GC–MS
This study shows that data acquired using the new Centri® automated multi-mode sampling and concentration system for gas chromatography–mass spectrometry (GC–MS) can be used to generate useful insights into the aroma profiles of foods. In the example investigated, the headspace profiles of two apple cultivars are sampled onto sorbent tubes, which are then analysed on Centri. The results of this analysis are then correlated with consumer sensory experience to highlight key volatiles of interest.

Application Note 251: Screening foods and beverages for butylated hydroxytoluene (BHT) using automated headspace–trap GC–MS
This study shows that headspace samples acquired on the new Centri® automated multi-mode sampling and concentration system for gas chromatography–mass spectrometry (GC–MS) can be used to screen food and beverages for trace-level additives. A breakfast cereal and a tea infusion were investigated, and the antioxidant BHT detected in both samples at the ng/g level, along with a range of aroma compounds.

Application Note 252: Quantitation of residual solvents in food packaging by automated headspace–trap GC–MS
This study shows that headspace samples acquired on the new Centri automated multi-mode sampling and concentration system for gas chromatography–mass spectrometry (GC–MS) can be used to screen food packaging for residual solvents and other additives. Analysis of a sample of a thin composite polymer used to contain savoury snacks found ethanol at 1.92 mg/m2, in addition to a number of other volatile compounds resulting from the manufacturing process.

Application Note 254: Identifying low-level odorants in wine by automated high-capacity sorptive extraction with GC–MS
This study shows that immersive sorptive extraction using high-capacity HiSorb probes, automated on the new Centri multi-mode sampling and concentration system for gas chromatography–mass spectrometry (GC–MS), can be used to screen wine for ppb levels of two yeast-derived spoilage compounds, as well as a range of other compounds.
