32 Agilent Microwave Plasma Atomic Emission Spectrometers User’s Guide
SVS 1/1+
For safety information and to prepare the SVS 1 or SVS 1+ for
installation, please see the instructions that came with the accessory.
The SVS 1/1+ is a 4-port switching valve positioned between the
spray chamber and the peristaltic pump of the spectrometer. During
the rinse time, when the instrument is usually idle, the autosampler
cleans the probe and presents the next sample for measurement,
increasing productivity. Excess sample is diverted away from the
spray chamber immediately after measurement, reducing sample
carry-over.
SVS 2
For safety information and to prepare the SVS 2 for installation,
please see the instructions that came with the accessory.
The SVS 2 increases sample throughput and decreases turnaround
time and operating costs. The SVS 2 features triple-stacked, 4-port
switching valve positioned between the spray chamber and the
peristaltic pump of the spectrometer. Samples are quickly loaded
into the SVS 2 sample loop, ready for immediate analysis by the
MP-AES, greatly reducing sample uptake delays. Pre-emptive rinsing
of the sample line means analysis times are reduced. The SVS 2 also
features an internal T-piece within the valve, reducing dead volume
and providing online addition of internal standard and ionization
buffer solutions. A bubble injector automatically injects bubbles after
the sample is loaded into the loop, isolating the sample from the rinse
solution. This reduces the volume of sample required for
measurement as tailing (or dilution) effects are minimized.
Agilent 4107 Nitrogen Generator
For safety information and to prepare the nitrogen generator for
installation, please see the User’s Guide that came with this
accessory.
