Product Description


The Dionex AS-50 autosampler and thermal compartment are used for high performance liquid (HPLC) and ion-exchange chromatography (IC). The autosampler syringe is capable of 1 to 99 injections the vial uses 0.3, 1.5,10 mL. The AS50 thermal compartment heats or cools the sample to equilibrium before it enters the column and can incorporate dual detector cells that identify conductivity and amperometry.
This Dionex autosampler and thermal compartment were acquired with a Dionex 50 series HPLC system. The AS50 sampler is in good cosmetic condition with minor signs of relocation and age which includes plastic scuffs. The thermal compartment was spritzed with the postassium hydroxide eluent that was not removed when the product was shipped to NLS. The cosmetic damage has not hindered the functionality of the autosampler nor the thermal compartment.
The instruments were tested by New Life Scientific technicians to power on and pass initialization. The instrument can be operated using the front panel of the instrument or with the PeakNet software using the DX LAN port; the software can be purchased along with a user license from Dionex, but NLS does not have the estimated costs for this. The autosampler includes a Kloehn 3000-series syringe pump. The thermal compartment includes a Rheodyne 9750 6-port fluidic platform that is usually a PEEK or stainless steel standard option. This 9750E has rebuild kits and tools available online from a number of  major scientific retailers, for any future maintenance needs. A detector cell is installed in the thermal compartment, housing a gold (Au) reference and disposable electrodes. There are two new Dionex vial and slip septum kits , one unopened (Au) disposable electrode on PTFE sheets package, and one opened sleeve of disposable electrodes.
