1088 Rotary Autosampler Autosampler for the Aurora 1030 TOC Analyzer • Automates introduction of 88 samples to the Aurora 1030 TOC Analyzer • Configurable for pre-acidication and sparging of sample TIC content within the autosampler to reduce TOC analysis time • Performs programmable rinse steps via an integral wash station to clean the sampling needle and prevent crosscontamination • Magnetic stirring ensures insoluble and particulated samples are homogeneous for accurate results • Fits directly under the Aurora 1030 TOC analyzer to minimize laboratory benchspace requirements • Supports sampling from open vials and septum piercing of sealed vials Description and Function Principal Applications • Drinking water • Wastewater • Ultrapure water • Cleaning validation • Water for injection • Groundwater • Surface water • Industrial process water • Seawater Sampling Methods • Open vial • Septum piercing The 1088 Rotary Autosampler is specifically designed to operate with an Aurora 1030 TOC analyzer. The 1088 autosampler aspirates liquid samples from vials and transfers each sample aliquot to an Aurora 1030 TOC analyzer for analysis. A removable 88-position autosampler tray loads the sample vials for fully automated, unattended operation. The 1088 supports a number of special functions to address a range of sample conditions and analysis requirements. Onboard magnetic stirring ensures samples containing insoluble components or particles are homogeneous for sampling and accurate analysis. Septum piercing provides closed vial sampling for applications where open vials may comprise the accuracy of measurements. System configuration for sample pretreatment allows pre-acidification and purging of samples within the 1088 prior to sampling. This technique removes the TIC content of samples, reducing the analysis time required for TOC measurements. Operating Principle The sampling sequence of the 1088 autosampler is user-programmed through the Aurora 1030 touchscreen display. A stepper motor drive positions the appropriate vial below the sampling needle. The needle mechanism then lowers into the vial, aspirates the specified sample volume, and transfers it to the reaction chamber of Aurora 1030. Following sample transfer, the sampling needle returns to a wash station to be rinsed. A user-programmable number of rinses are then performed to clean th
