Assessing SIFT-MS Method Feasibility (Procedure 1)
The marked difference in the analytical approach of SIFT-MS compared with the conventional GC and LC techniques means that the feasibility of method transfer – or new method development – for SIFT-MS should be evaluated prior to experimental work. Drawing on principles discussed in Part 1 of this book, this chapter describes a procedure by which the ...openaire +1 more source
Modifying an Existing SIFT-MS Method (Procedure 7)
SIFT-MS, with its chromatography-free, soft chemical ionisation approach to the analysis of volatile compounds requires different procedures for modifying validated test methods compared to GC. This chapter provides procedures for modifying SIFT-MS methods involving addition or removal of analytes, modification to product ion selections, a change of ...openaire +1 more source
Preparing the Automated SIFT-MS Instrument for Analysis (Procedure 2)
Selected ion flow tube mass spectrometry (SIFT-MS) instruments have different operational procedures compared to conventional chromatographic instruments, since they are based on different principles. This chapter describes, in a general manner, how to prepare a SIFT-MS instrument for analysis, together with a coupled robotic autosampler. Additionally,openaire +1 more source

Measuring VOCs in Christchurch ambient air : using SIFT-MS technique
2002The project is aimed at monitoring the volatile organic compounds (VOCs) that may be regarded as undesirable in Christchurch's ambient air. Nine VOCs viz NH3 (ammonia), C2H4 (acetylene), C3H6OH (methanol), C2H5OH (ethanol), CH3CHO (acetaldehyde), C6H6 (benzene), C7H8 (toluene) and C8H10 (xylene) were-selected to be examined diurnally and seasonally ...
