UWPR NSI Source
The UWPR nanospray ionization (NSI) source was designed to be used on the Ion MaxTM source on ThermoFinnigan instruments (LTQ and TSQ series). It offers all the benefits and features of commercial NSI sources:
- Lower flow rates: no drying gas or thermal heating is required and increased sensitivity compared to higher flow ESI
- Higher tolerance to a wide variety of liquid compositions than conventional ESI
Additionally this new NSI source offers significant improvements over most commercial NSI sources:
- Great flexibility: it accommodates in house packed columns of all length, commercial columns, as well as configurations with traps, spray tips etc.
- The source can be customized to your specific needs: e.g. mounting of cameras, LED lights or anything else you can think of
- Additionally this NSI source can be used in conjunction with the Finnigan NSI probes (static , dynamic and packed tip probe)
- The open design allows for leaks to be detected immediately
- Significantly lower cost
- The NSI platform can also be used with the adaptor ring of the Finnigan NSI source, eliminating the need to machine the adaptor bracket
- All the parts are commercially available, except for the adaptor system (custom machined, e.g. by emachineshop.com)
The UWPR is currently using the NSI source on all of our Thermo instruments.
The plans for this NSI source are available for free for academic, non-commercial use, please contact Priska D von Haller, e-mail: priska@u.washington.edu
