Refurbished Waters/Micromass ZQ Mass Spectrometer (p/n 186002000) complete with PC including MassLynx 4.0, E2M28 vacuum pump, ESI and APCI probe. OPTIONAL: Waters 2795 Alliance HT Separations module (p/n 800000123), Waters 2996 Photodiode array detector, Waters column heater (p/n WAT270852), Sedere Sedex 75 ELSD and UPS. The ZQ can perform up to 32 MS experiments in a single chromatographic run. You can cycle through any combination of full-scan, single-ion recording (SIR), positive ion, negative ion and variable cone voltage functions all in one injection. Mass Range: 2040 amu. (it may also be available with 4096 amu). Acquisition rates up to 5000 amu/sec using a state-of-the-art Embedded Personal Computer Acquisition System (EPCAS). 

A popular single quadrupole mass spectrometer worldwide, it offers characteristic performance and robustness for laboratories that require nominal mass resolution for mass confirmation applications. The ZQ Mass Spectrometer is built using the technical innovation you expect from Micromass brand products. The ZQ's distinctive features include:

* Small footprint (Width x Height x Depth): 390 mm x 587 mm x 810 mm
* 2040 or 4096 amu upper mass limit
* Acquisition rates up to 5000 amu/sec using a state-of-the-art Embedded Personal Computer Acquisition System (EPCAS)
* ZSpray dual orthogonal sampling interface provides unsurpassed sensitivity and ruggedness
* Vertically mounted liquid inlet probes to minimize tube length and peak dispersion
* Software-controlled, integrated syringe pump for easy calibration, tuning and sample infusion
* Software-controlled divert valve/manual injection valve
* Digital control of source gas flow rates
* Differentially pumped vacuum system featuring singular air-cooled, split flow turbomolecular pump technology
