4000 MiD mass spectrometer with automated sampling unit
Article No.: A66900

Chip-based miniaturized mass spectrometer - Delivery starts soon!

The 4000 MiD is a miniaturized chipbased single quadrupole mass spectrometer suitable for a broad range of applications. An integrated oil-free pump system enables a small footprint and thereby the installation of this detector nearly everywhere.

The easy to use concept with plug and play consumable results in low maintanance costs and a completely tool-less front end. Due to it‘s small design the nitrogen consumption of the 4000 MiD is reduced leading to low operating costs. With the MiDas automated sampling unit the 4000 MiD is the ideal addition for preparative HPLC systems and mass directed purification.

With the integrated vacuum system and integrated electronics inside of one box the KNAUER 4000 MiD brings mass spectrometry to places where no other spectrometer can be deployed.

With a mass range of 800 m/z the KNAUER 4000 MiD can be used for a borad variety of applications. In combination with the KNAUER MiDas it is the ideal choice for preparative chromatography and direct indroduction methods.
The mass spectrometer can be controled with ClarityChrom® 7.4.1 and higher allowing it to be integrated into KNAUER LC systems.
