“…GC × GC can be coupled to time-of-fl ight mass spectrometry (TOFMS) because it offers the fast acquisition rate required for accurate characterization of GC × GC peaks that have a width at the base of 100 to 250 ms. Sector and ion trap MS that are popular in the environmental fi eld can barely be used because of the time it takes for those instruments to scan even a limited number of masses (SIM) and move to another mass cluster. TOFMS can acquire at rates up to 500 scans per s (Leclercq and Cramers, 1998 ), which corresponds to 50 data points per 100 ms peak. Contrary to sector, quadrupole, and traps operating in SIM mode, a full mass spectrum is collected during each TOFMS acquisition.…”

“…Mais tarde, outros autores também apresentaram estudos teóricos relacionados à otimização da técnica. 4,5,[13][14][15] Uma abordagem mais detalhada das equações que fundamentam a técnica será apresentada adiante.…”
Section: Breve Histórico Da Redução Do Tempo De Análise Em Cromatogra
unclassified“…Colunas de dimensões reduzidas são fundamentais para a diminuição no tempo de análise e obtenção de cromatogramas bem resolvidos, constituindo o primeiro passo em direção a separações ultrarrápidas. 4,8,15,16,18,19,28,35 A variação do d.i. em uma coluna cromatográfica promove um balanço entre dois fatores: a eficiência da coluna (determinada pelo número de pratos teóricos -N) e a capacidade da coluna (relacionada à quantidade de amostra que pode acomodar a coluna sem causar distorção ou perda de resolução dos picos).…”
