AOC-20i/AOC-20s - Features
Auto Injector/Auto Sampler for GC/GC-MS
The AOC-20 provides the highest degree of reliability.
Reproducibility and reliability are what make an auto injector valuable to a laboratory. Reproducibility can be adversely affected not only by less than optimum injection conditions, but through sample evaporation as well.Reliability is a measure of how well the instrument faithfully reproduces injection of the sample. The AOC-20i ensures that both of these needs are met.
To illustrate typical reproducibility of different types of compounds and demonstrate the inertness of the GC injection port, a 500 ppm Grob test mix standard sample was injected 10 times.
Note that the coefficient of variation (C.V.%) was less than 0.3% for all compounds. Also note that neither the acidic (peaks 2 & 3) nor the basic compounds (peaks 5 & 8) show any evidence of tailing, indicating the inertness of the sample path in the GC.
Note that sample reproducibility can vary significantly based upon the type of sample and the analytical conditions used.
The results presented are illustrative and are not guaranteed for all sample types and analyses.
Attachment and removal are easy.
Flexible sample handling of up to 150 vials, greatly enhances laboratory productivity.
The AOC-20s Auto Sampler carousel and robotic arm provide for sample transport to the AOC-20i Auto Injector using 1.5 mL and 4.0 mL vials. The system is smart too! It can tell the difference between the vial types by reading the information from the vial tray in use. The AOC-20i/AOC-20s is a powerful automation tool for the GC laboratory that allows the user to take full advantage of the GC system's capabilities.
