WebThe GC/MS interface consisted of short piece of 1/8 inch OD copper tubing wrapped with heat tape. A thermocouple was used to check the interface temperature. The GC column extended about 1 cm from the tubing into the heated gas stream of the DART ion source and positioned directly in front of the sampling orifice for the mass spectrometer ... WebThe interface temperature is set above the boiling point of the highest-boiling component of the sample. The exhibit is a GC/MS interface from the 5972 MSD single quadrupole mass detector manufactured by Hewlett …

Webthe temperature limit is reached. Any peaks that elute during isothermal temperature conditions substantially increase in width as peak retention increases. 9 Extracted samples often contain compounds that elute after the last solute of interest. The final temperature and/or hold time need to be large enough to ensure elution of these compounds. WebThough the interface design is similar to ESI, the ionization principle differs, making it more suitable for low- and medium-polarity compounds (non-polar molecules).
