This refurbished ZQ 4000 system has been fully tuned and calibrated October 2016. Single quadrupole mass spectrometer from Micromass with Alliance and 2487 UV. Capable of performing up to 32 MS experiments in a single chromatographic run.
See full tune and calibration data files for download.
The Waters 2695* Separations Module consists of a quarternary pump, degasser and a variable volume autosampler, capable of injecting from 5 x 24 2ml vials
*Note: Images display a 2690 badge - this unit has been upgraded to 2695 specification.
The four solvent in-line degasser offers a high efficiency alternative to helium sparging for the removal of dissolved gases from HPLC mobile phases.
Designed for a wide variety of applications, this reliable tool is a common work-horse in most analytical and contract labs. Built to meet labs rigorous requirements or routine analysis, suited to Pharmaceutical, Food Safety, R&D, Chemistry, Environmental or Quality Control labs. Featuring a large, easy-to-use LCD interface, take advantage of the quick autostart and optimize your methods with a simple push of a button. Manage up to 120 industry standard vials with the built in autosampler.

2487 UV/Vis Detector
The 2487 detector is a 2 channel, tunable ultraviolet/visible (UV/Vis) detector that operates in single or dual wavelength mode, allowing spectrum scanning using a flow cell or a cuvette, providing RatioPlot and MaxPlot functions.
Single Wavelength Mode Single wavelength is the default mode of operation for the 2487, supporting monitoring of a single wavelength from 190nm to 700nm, settable in 1nm increments on Channel A.
Dual Wavelength Mode In dual wavelength mode, the detector monitors on Channel A and Channel B. The sampling frequency is reduced from 10Hz to 1Hz, limiting use of this mode to more standard chromatography, where peaks span at least 20 seconds to enable full characterisation of a peak.
Stand-alone programmability - Stores up to 10 user defined programs (or methods) consisting of up to 16 programmable timed events and 2 threshold events each.
Integral erbium calibration reference - ensures wavelength accuracy
Automatic second order filter - Automatically enganged for wavelengths 370nm and greater and removed for wavelengths 369nm or less.
Spectrum scan and storage - supports spectrum scan, display, subtraction, storage and playback, in addition to standard tunable absorbance and UV/Vis functionality.
Cuvette qualification - facilities qualification of the detector by insertion of a standard in a cuvette without breaking any fluidic connections.
Cuvette sample analysis - allows the spectrum of any sample placed in the cuvette to be recorded.
Method editing and storage - supports basic method programming, storage and retrieval from the front panel
Full diagnostic capability - supports built in diagnostic tools to optimize functionality and performance.
Backward compatibility - operates as a 486 detector with Millenium Chomatography manager version 2.1n and lower, PowerLine, ExpertEase and other Waters products connected via the LAC/E interface using the IEEE-488 bus.
Wavelength range: 190nm to 700nm
Accuracy: ± 1nm
Sensitivity setting range: 0.0001 AUFS to 4.0000 AUFS

Why employ ms4sale?
Your MS options are far reaching, so why use Jaytee Biosciences? Unlike other providers of used MS equipment, we have the ability to completely:
This is because we employ both skilled engineers and experienced scientists, which allows us to provide a value added solution.
When we acquire an MS system, we are not simply re-listing for sale with a mark-up. We service,test and run the system, producing chromatographic and mass spectral data before we advertise. When our clients ask us whether a particular system is suitable for their application, we provide detailed information, and offer a pre-visit service whereby you send us your sample, which we run and prove for your benefit. Why? Because we can, and because it helps you make the right choices.
Ask yourself why other companies are only showing stock images, with no data or proof of performance - because we have the skills, you get the peace of mind and the ongoing support for your method.
Finally, this is at no added cost, since our pricing policy is flexible, and therefore competitive - a win/win!
Jaytee; No take overs/mergers in over 35 years - just professional, solid, skilled on going support.
