Syrris introduced the Atlas Autosampler Module and Autosampler Probe which, when connected to one of the company's Atlas Syringe Pump valves, aspirates up to six samples from the reactor at user-defined intervals. This autosampler allows automated dosing to a reactor from one syringe, while taking six samples using the other syringe or simply taking 12 samples.
The Autosampler Module holds six 2-mL HPLC vials and can be mounted on the provided support rods. The syringe pump with 6-port selection valve can then sequentially aspirate samples from the reactor into the vials using the Autosampler Probe, which is located after the Autosampler Module. The probe consists of six polytetrafluoroethylene (PTFE) pipes encased in a chemically-resistant PTFE and glass sheath. It can be placed inside a jacketed reactor lid port, and connected to the module.
The Atlas Syringe Pump is a flexible module for volumetric dosing that consists of two syringes with 6-port valves and can be configured into either two refilling flows or one continuous flow. A choice of dosing modes allows simple reagent additions or the active control of parameters, such as pH and temperature, using Atlas sensors. With the ability to be operated in standalone mode or be controlled via the Atlas base unit or PC software, users are provided with a versatile instrument that allows automated reagent addition or autosampling with data logging.
