“…Program rates of 1000 8/min. and more can be achieved in modern high speed capillary column GC [158]. Typical arrangements are based on insertion of fused silica tubing into stainless steel enclosures which are then subjected to surges of electrical power [159,160].…”

“…The Ultrafast module (UFM) adopted here was that described by Magni et al [5] affording temperature programming rates up to 20 • C/s. It derives from the Overton's system [7] for heating very short (1-2 m) narrow bore columns to be installed in a portable Ultrafast GC [8]. This system incorporates heating and temperature sensing elements distributed along the column.…”

“…19,28,40 A ideia do aquecimento resistivo direto da coluna surgiu na década de 60, mas teve sua eficácia experimental comprovada somente a partir dos anos 90, quando diferentes propostas deste sistema foram publicadas na literatura. [40][41][42][43][44][45][46][47][48][49][50] A partir do trabalho de Ehrmann et al 40 e das patentes de Mustacich et al [47][48][49] e Magni et al 50 foram concebidos os diferentes módulos de aquecimento ultrarrápidos comercializados atualmente, projetados para comportar colunas de vários comprimentos e que podem ser instalados tanto em cromatógrafos convencionais quanto em sistemas portáteis de análise cromatográfica. Esses módulos de aquecimento resistivo da coluna permitem atingir taxas de aquecimento de até 20 o C s -1 , sendo que o resfriamento da coluna é rápido, indo de 350 a 50 °C em cerca de 1 min.…”
