摘要: The standard configuration split ratio of 20-40:1 reduces analytical sensitivity because most the headspace volatiles are vented through splitter rather than passing to column. For an investigation clinical significance cows' milk increase in without a reduction resolution or sample throughput was required. A splitless transfer column fulfilled these requirements
