APPLICATIONS

TECHNICAL NOTE: OVERCOMING THE LIMITATIONS OF SPLIT/SPLITLESS INLETS USING LARGE-VOLUME INJECTION

This paper provides a short overview of the drawbacks of split/splitless inlets used for GC, and how these can be tackled through large-volume injection (LVI) using the OPTIC-4 multi-mode inlet from GL Sciences.

IMPROVED CHARACTERISATION OF MATERIALS USING PYROLYSIS WITH GC×GC–TOF MS

Pyrolysis coupled with two-dimensional gas chromatography and time-of-flight mass spectrometry (Py–GC×GC–TOF MS) can be used for quality control of consumer products, including tyres, plastics and paper.

FAST ANALYSIS OF SEMI-VOLATILE ORGANIC COMPOUNDS USING PTV-GC–TOF MS

This study demonstrates the improvements in efficiency and sensitivity that can be achieved by using programmed temperature vaporisation (PTV) with GC and time-of-flight mass spectrometry (TOF MS) for the analysis of semi-volatile organic compounds relevant to environmental monitoring.
