1088 Rotary Autosampler
Autosampler for the Aurora 1030 TOC Analyzer
• Automates introduction of 88 samples to the Aurora 1030
TOC Analyzer
• Congurable 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

The 1088 Rotary Autosampler is specically 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 conguration
for sample pretreatment allows pre-acidication 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 specied 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 the needle before the
next vial is sampled.
