“…These plots fit a log-normal distribution more exactly than to a Gaussian distribution. Although chromatographic peak tailing has been attributed to slow adsorption-desorption processes or voids in the stationary phase [29], this deviation from Gaussian behavior may also be related to the square root dependence of solvent front distance from the bottom of the plate as a function of development time [30]. Linear regression of the solvent front distance versus the square root of the development time resulted in the following relationship:…”

“…Historically, TLC in all its forms has proved important in chemical and biochemical analysis (Poole and Poole, 1995). Despite its long history, TLC is still an evolving science (Poole, 2003) and its simplicity and cheapness makes TLC an attractive methodology for metabolomics.…”

“…Além disso, a TLC pode ser usada quando as possibilidades de aplicação de outros métodos são limitadas pelas propriedades da amostra, como por exemplo, substâncias termolábeis, baixa volatilidade ou presença de quantidades consideráveis de impurezas dificultando a análise (resinas, pigmentos, etc.) [5][6][7] . O sucesso da separação cromatográfica depende do método de detecção.…”

“…O uso combinado de vários reagentes de detecção ajuda na identificação de tipos ou classes de compostos, mas não na identificação do composto individual. A única solução para a identificação é o uso combinado de técnicas [5][6][7] . A tomaticultura, apesar de ser uma cultura rentável, costuma atravessar fases críticas devido à ocorrência freqüente e constante de pragas durante todo o ciclo da planta.…”
