The laser diode thermal desorption (LDTD)™ 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 LCMS-8060 system, equipped with an LDTD ion source (US Patent 7, 321, 116, Phytronix Technologies Inc.), delivers solutions that complement screening and identification testing in various fields such as medicine, clinical and food safety.
Unlike LC-MS, LDTD requires no mobile phase, enabling reduced background noise during measurements. The sample is heated and desorbed by a laser diode as a neutral molecule in the gas phase. These molecular species are ionized using atmospheric pressure chemical ionization (APCI) by corona discharge. This thermal desorption process produces molecular ions in a very short time.
The instrument's outstanding design ensures that laser diode thermal desorption and atmospheric pressure chemical ionization (APCI) are performed rapidly on the sample to be analyzed.
