SIS Newsletter

Covers SIS products, services, promotions, news, and other mass spectrometer related information.

28 Aug 2013: Nanoliter Dispensing Devices can be used to place media on the MALDI plates for MALDI/TOF instruments, but the most exciting ability of this device is to collimate droplets directly into the ion source like electrospray (ESI), the unique concept being that nearly 100% of the droplets go directly into the source versus <1% from ESI, giving a huge increase in sensitivity. We believe this could be the next big advance in LC/MS sources. [NEW]
