Advanced Switching Valve-Avs 4, Avs 6 Or Avs 7 Switching Valve; Svs 2+ Productivity Package Accessory - Agilent Technologies 5100 Site Preparation Manual

Accessories and Options
Extra maintenance may be required on the SPS if it is operated in excessively
NOTE
dusty or corrosive conditions. Sample contamination from airborne particles is
eliminated and corrosive or toxic fumes are removed during sampling with the
optional environmental enclosure.
An Agilent-supplied trolley is available for the SPS. A drain vessel
must also be accommodated.

The integrated AVS 4 (4 port switching valve) rinses the sample
introduction system while the next sample is being presented to the
instrument prior to measurement. Excess sample is diverted away
from the spray chamber and rinse introduced immediately after
measurement, reducing sample carry-over and reducing cleaning
frequency of sample introduction components.
The integrated AVS 6 (6 port switching valve) and AVS 7 (7 port
switching valve) increase sample throughput and decrease
turnaround time and operating costs. The switching valve is
positioned between the nebulizer and the peristaltic pump of the
spectrometer. Samples are quickly loaded into the sample loop, ready
for immediate analysis by the ICP OES, greatly reducing sample
uptake delays. Pre-emptive rinsing of the sample line means sample
to sample analysis times are reduced.
The AVS 6 and AVS 7 include a bubble injector that automatically
injects bubbles after the sample is loaded into the loop, isolating the
sample from the rinse/carrier solution. This reduces the volume of
sample required for measurement (therefore reducing analysis time)
as tailing (or dilution) effects are minimized.
