Agilent 5100 and 5110 ICP-OES Site Preparation Guide 51
The SVS 2+ increases sample throughput and decreases turnaround
time and operating costs. The SVS 2+ switching valve is positioned
between the nebulizer and the peristaltic pump of the spectrometer.
Samples are quickly loaded into the SVS 2+ sample loop, ready for
immediate analysis by the ICP-OES, 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.
5-Channel Peristaltic Pump
The five channel peristaltic pump can be used for for additional
solution introduction and is required when using the MSIS accessory.
External Inlet Duct Adapter
The External Inlet Duct Adapter provides greater filtration for use in
labs with harsher environments.
Vapor Generation Accessory (VGA) Recommended Gases
The VGA is fitted with 6 mm (1/4 inch) internal diameter flexible
hose for connection to a standard barbed tail connector, which must
be supplied by the customer.
CAUTION
The gas supply for the VGA must be a separate regulated line, to prevent
exceeding the maximum inlet pressure to the VGA.
NOTE
The VGA allows a 45 mL/min flow of argon to pass through it even when it is
switched off. It is recommended that the argon gas line is fitted with a stop valve
to shut off the gas supply to the VGA.
