Automated Liquid Sampler (ALS)

The 7693A ALS is a completely new design, offering substantial gains in throughput, flexibility, sample preparation automation and serviceability for all current Agilent (Germany) benchtop GC models. The new ALS is modular, letting users configure the exact autosampler they need – starting from a basic injector with a 16-sample turret, and later adding capabilities as needs expand. Options include a second injection tower, a 150-vial sample tray and a vial heater/mixer/barcode reader for long unattended operation.

Agilent’s exclusive fast-injection technology is twice the speed of any competitive ALS. Injection time of less than 100 milliseconds minimizes sample degradation and the effects of needle discrimination. The two-injector configuration doubles sample throughput.

Agilent offers an optional Heater/Mixer/Barcode Reader module that can automate a number of pre-injection procedures. This offers substantial savings in time and labour, and operator-to-operator variability is eliminated. Solvent consumption and waste expense can be trimmed by as much as 90 percent.
