The Niagara Plus uses Flow Injection technology to reduce analysis time, environmental impact and operating cost:
- Lower argon consumption
- Reduced cost of consumables such as torches, cones, RF coils, pump tubing, acids, standards and chemicals
- Lower power consumption
- Reduced stress on RF system and lower maintenance cost
- Less down-time for cleaning carbon from torch when analyzing organics
- Less chemical waste to dispose of
In addition to the cost and environmental benefits, the Niagara Plus delivers a major improvement in analytical performance:
- Twice the sample throughput for a typical analysis
- Half the normal sample volume
- Automatic addition of the internal standard simplifies sample preparation
- Inert sample path reduces carryover - the sample does not contact any peristaltic pump tubing
- Constant flow of solution to the plasma maintains plasma stability and reduces stabilization times
- Compact design easily interfaces to almost all models of ICP-MS and ICP-OES
The Niagara Plus provides enhanced performance through unique design features:
- Bubble Injector: The Niagara Plus automatically injects several air bubbles at the end of the sample plug while filling the sample loop. These air bubbles prevent boundary diffusion and do not allow the sample to mix with the carrier solution. This allows a smaller volume of sample to be used and further reduces the analysis time. Because the bubbles are injected at a programmed time they are never introduced into your nebulizer, thus avoiding any plasma disturbances.
- Time In Sample (TIS) option: This feature allows you to program the time the autosampler probe sits in the sample tube, instead of waiting until the loop is filled. This prevents the sample in the uptake lines from being wasted, further reducing the amount of sample consumed. Combining the Bubble injector and TIS the Niagara Plus can save up to 55% of the sample compared to a system without these features.
- Built-in internal standard tee: This low volume removable mixing tee allows the operator to tee in diluent or internal standard without significantly lengthening either the equilibration time or washout time. If you select not to tee in an internal standard or diluent, the tee can simply be removed from the valve.
- Programmable Uptake Pump: The method wizard calculates the optimum pump speed for the length of the uptake tubing, including the autosampler probe and sample loop.
New Control Module
The new Niagara Plus CM is controlled by a dedicated control module rather than the instrument PC. The benefits are:
- Faster communication, resulting in even higher sample throughput.
- The option of running unattended without any connection to the instrument PC once the method has been loaded.
- Simplified installation.
