Model: Varian HPLC Binary Gradient with PDA/DAD & 320-MS Quadrupol Mass Spectrometer (2009)


The 212-LC LC/MS (liquid chromatography/mass spectrometry) pump is designed to meet the needs of scientists working in a variety of application areas ranging from environmental to pharmaceutical. The 212-LC is an advanced low delay volume chromatography pump ideal for laboratories performing research or routine LC/MS analyses with industry-standard 2 mm columns. Typical applications include the analysis of trace level compounds in foods, environmental samples and in biological matrices where high sensitivity, high throughput and precise quantitation are critical.

The 320-MS delivers high sensitivity with low noise and less maintenance. The patented API interface, with its dual off-axis needle and capillary provides efficient desolvation with minimum contamination. A high performance skimmer and quadrupole ion guide allow maximum ion transmission for outstanding signal intensity. Varian’s patented 180º curved collision cell provides additional noise reduction for difficult matrices. You get the benefits of a detector that is off-axis to the source without the use of a conversion dynode.


- Switch from LC to GC interface and back again   
- Change ionization modes between ESI and APCI   
- GC sources include: EI, PCI and NCI   
- Single Quad to Triple Quad upgrade   
Flexible, Rugged, Sensitive   
Varian’s patent pending, computer-controlled gas temperature (SelecTemp™) and flow (SelecFlow™) give you the flexibility to develop methods with greater ruggedness and sensitivity. An integrated syringe pump and six port valve, with time-programmable software control, accelerate method development.   
Sensitivity When You Need It   
When we say femtogram sensitivity, we mean it. Whether you’re doing simple flow injection with the built-in syringe pump (Figure A), or on-column analysis using the new 212-LC pumps (Figure B), you’ll be impressed with the 320-MS sensitivity.
