A Sub Atmospheric Pressure MALDI (Sub-AP/MALDI) Source

Based on the next generation (ng) platform, we are proud to introduce our Sub-AP/MALDI source.

Combined with MassTech’s Ion Funnel technology, you can push the boundaries of mass range and limits of detection for a variety of purposes.  More Info


Welcome to MassTech!

The Leader in AP MALDI Development and Applications

MT Explorer 50

Say hello to our internally developed, MS-n capable 3D ion trap spectrometer, the MT Explorer 50.  Developed with field deployability and portability in mind, you can now bring laboratory level analysis with you wherever you want to go and with an atmospheric pressure interface, use almost any source you want!

2011 ASMS Complete

We would like to thank everyone who came by our booth during the 2011 ASMS conference in Denver, Colorado. This was the first year we exhibited our newest product – the MT Explorer 100 – and it was well received. For the remainder of 2011, we will be ramping up production, but limited numbers force us to sell our mass spectrometer within the continental United States. Beginning in 2012, we expect to be able to ship in large numbers and…
