Book 1995nts. In the intervening period, the scope and technical capabilities of instrumentation for analysing dyes and pigments has significantly expanded. It is now possible to rapidly resolve a number of problems whose solutions were previously either unattainable or very difficult to achieve. For instanc

Behnaz Jahanbin,Vahid Soleimanipanded the range of compounds that can be analyzed using mass spectrometry, there is still no single technique that is suitable for the analysis of all classes of dyes. Therefore, gas-phase ionization techniques such as electron impact and chemical ionization remain necessary and useful for the analysis of volatile compounds.
