The single quadrupole GCMS-QP2020 NX offers the possibility to detect analytes in Scan and SIM modes individually or simultaneously over a mass range of 1.5 - 1,090 m/z. The EI source provides excellent selectivity, and the inherent fragmentation of this ionization type allows for quick identification of compounds by library searching (NIST library is installed). The instrument integrates with a multifunctional AOC-6000 autosampler enabling a fully automated easy-to-use system and continuous operation combining different sample introduction methods, including liquid injection and headspace injection.
