- Faster throughput
- Lower cost
The Niagara Plus system uses Flow Injection technology to reduce analysis time and cost.
- Twice the sample throughput for a typical analysis
- Automatic addition of the internal standard simplifies sample preparation
- Inert sample path reduces carryover – the sample does not contact any peristaltic pump tubing
- Reduced cost of consumables – longer lifetime for torches and cones, lower argon cost
- Constant flow of solution to the plasma maintains plasma stability and reduces stabilisation times
- Compact design easily interfaces to almost all models of ICP-MS and ICP-OES
- The Niagara Plus utilizes a positive displacement pump to rapidly fill a sample loop and a proprietary valve with extra low sweep volume to provide the ultimate in ICP productivity.
Typical cycle time for Niagara Plus compared with standard ICP system.
Step 1 – Fill loop
The positive displacement piston pump rapidly fills the sample loop. At the same time, rinse and internal standard solutions are delivered to the nebulizer, washing out the nebulizer and spray chamber, and ensuring that plasma stability is maintained.
Step 2 – Aspirate sample
The Niagara valve switches position so that the rinse solution pushes the sample into the nebulizer. The internal standard is mixed with the sample within the valve. At the same time, the autosampler probe and sample uptake tubing are rinsed by the piston pump. Note that the sample does not contact the peristaltic pump tubing at any time.
