Phytronix LDTD 960 source (arrived with Waters XEVO TQ-S). The Phytronix LDTD-960 Laser Diode Thermal Desorption Ion Source is a direct ion source for mass spectrometers that provides users with exceptional, high-throughput performance. This innovative technology enables ultra-high speed analysis in less than 4 seconds per sample. The LDTD ion source can be installed on most Waters mass spectrometers. The new universal ion source housing (ESI, APCI, ESCIR, APPI, TRIZAIC UPLC and nanoFlowTMESI) is used as an interface for the LDTD. Therefore, any Waters mass spectrometer equipped with the new universal ion source housing is compatible. Please contact us for complete Phytronix source details.
