Hyphenated Techniques Offer Greater Specificity

摘要

What is a hyphenated analytical technique? The answer, according to a chapter on "Hyphenated Techniques" in Analytical Chemistry (Wiley-VCH, 1998), is "the marriage ... of two separate analytical techniques via appropriate interfaces, usually with thebackup of a computer tying everything together." In general, the term hyphenated techniques ranges from the combination of spectroscopic techniques (e.g., mass spectrometry) with chromatographic techniques (e.g., liquid chromatography or gas chro-matography), or the coupling of separation techniques with spectroscopic detection techniques.
