Tempo™ LC MALDI Plate Spotting System
The Tempo™ LC MALDI Spotting System provides high precision plate spotting technology. It provides robust, contact-free electrostatic deposition of droplets and includes a three-channel micro-LC pump for the LC gradient and post-column addition of MALDI matrix. For greater throughput and automation, the system accommodates multiple plates and multiple LC runs per plate. An integrated autosampler and low-dispersion UV detector are also included.

Non-contact Deposition
LC MALDI frees MS analysis from the time constraints of LC to enable more in-depth interrogation of samples, which can be of particular advantage in applications such as large molecules separation or metabolite identification. The Tempo™ LC MALDI system dispenses droplets on plates by applying a high voltage electrostatic pulse on the sample needle at controlled intervals. This non-contact deposition technique virtually eliminates any occurrence of missed or misaligned spots and routinely delivers highly reproducible results and high-quality MS data.
