This listing is for a HP 5890 GC With 7673 autosampler controller and 6890 Injector HP 5890 GC HP 76 (more)73 Auto Sampler HP 6890 Injector The Hewlett Packard HP 5890 Series Gas Chromatograph is a chemical analysis instrument used for separating chemicals in a complex sample. This instrument uses a flow-through narrow tube known as the column, through which different chemical constituents of a sample pass in a gas stream (carrier gas, mobile phase); the constituents move at different rates depending on their various chemical and physical properties and their interaction with a specific column filling, called the stationary phase. As the chemicals exit the end of the column, they are detected and identified electronically. The function of the stationary phase in the column is to separate different components, causing each one to exit the column at a different time (retention time). Other parameters that can be used to alter the order or time of retention are the carrier gas flow rate and the temperature. This system has been removed from the lab while in good working condition, it was well serviced and is still in very good condition.Equipment can be serviced/renovated/refurbished on request at extra cost.

This listing is for a HP 6890 GC with Autosampler, Controller and 6890 Injector HP 6890 GC HP 6890 S (more)eries Injector HP Auto Sampler Controller G1512A The Agilent 6890 series GC features electronic pneumatic control of all gas pressures and flows. On board sensors automatically compensate for ambient temperature changes and barometric pressure differences to routinely achieve more accurate and reproducible results. By providing stable results, EPC reduces re-calibration frequency and improves laboratory productivity.

This listing is for a Varian 3900 GC with CP-8400 AutosamplerThe Varian 3900 gas chromatograph (GC)  (more)is designed to meet the demands of the analytical laboratory with its compact design—GC occupies less than half the workspace of the average gas chromatograph unit. Models 39001-00 and -05 feature an icon-based keypad which simplifies training and increases daily productivity. Select one of six pre-programmed languages for further ease-of-use. Password protection locks keypad from unauthorized access. Each Varian 3900 GC unit features a front access column compact oven with Precise Temperture Control which uses standard 7" (17.5 cm) diameter capillary columns. Maximum operating temperature is 450°C—accommodates any application. Plus, the oven cools down from 450°C to 50°C in only 5.2 minutes!

This listing is for a Varian Autosampler Model 410 unit on it's own. The Varian ProStar 410 HPLC Aut (more)osampler has variable injection volumes and automixing/autodiluting. The ProStar 410 is perfect for laboratories with changing needs. It provides flexible operation without sacrificing reliability or performance. Multiple injection modes for flexibility, ease of use, and precision. Full loop filloverfills the sample loop for maximum precision. Partial loop fill allows easily programmed variable injection volumes. Microliter pickup withdraws the exact amount to be injected without sample loss. The Varian ProStar 410 AutoSampler offers the best of both worlds. It is intelligent for research applications yet rugged enough for routine quality control work. With Pressure Assisted Sampling Aspiration (PASA), the Varian 410 ProStar AutoSampler applies pressure within the vial while the sample is withdrawn by a high-resolution syringe. Air bubbles and in-vial vacuum problems are eliminated resulting in excellent reproducibility. Flexibility with multiple injection modes Optimal performance with integrated column oven Biocompatible and sample cooling options available Specifications: Standard sample tray 84 x 1.5 mL vials with 3 x 10 mL vials Optional sample trays 96 x 2.5 mL vials or 24 x 10 mL vials Dispenser unit 50 µL syringe standard; 1000 µL or 2500 µL syringes, optional Injection volume 1 to 5000 µL with preparative option up to 10 mL Injection methods nine methods in memory Needle wash integrated, programmable large reservoir Vial detection Yes Reproducibility Full Loop: < 0.3% RSD Partial Loop: < 0.5% RSD Microliter Pickup: < 1.0% RSD Carryover < 0.05% Optional sample cooling 4°C to 15°C programmable Can be refurbished on request, refurbishment not included in price.
