The gas chromatograph mass spectrometer system boasts superior sensitivity thanks to its pre-filter mass analyzer and electron multiplier. When desorbing solids, it employs a controlled temperature range of 100 to 350?, while maintaining a steady flow rate of 1 to 1.5 ml/min. The analysis is characterized by its precision and specificity, facilitated by a meticulously crafted seven-stage temperature programming sequence. The interface temperature is meticulously maintained at 450?, ensuring optimal conditions for the separation and identification of compounds. This state-of-the-art GC-MS system combines cutting-edge technology to deliver exceptional sensitivity and accuracy in the analysis of complex samples, making it an invaluable tool for a wide range of scientific applications.
