10 good reasons why you should consider the Metrohm 797 VA Computrace instead of an AAS or ICP

The 797 VA Computrace from Metrohm is the modern PC controlled voltammetric workstation for the determination of trace metals - in addition many different organic compounds and anions can also be quantified – and thanks to the sophisticated intuitive software design the operation is unbelievably simple.

The 797 offers at least equal sensitivity for a fraction of the purchase price of an ICP or AAS instrument all backed by the Swiss guarantee of quality. The VA Computrace can be used as a standalone instrument or with differing levels of automation for higher sample throughput to meet application requirements.

Detection limits for heavy metals in the ng l-1 region, essential for the monitoring of ever decreasing regulatory consent levels required to meet new EU directives.

Extremely low running costs with no expensive flammable gases or lamp changes needed, the 797 requires only a single cylinder of nitrogen and good quality deionised water.

Voltammetry is a recognised technique with many official ISO, EPA, ASTM, AOAC and DIN standards plus the HMSO Blue Book Method for the "Determination of Some Trace Metals in Marine and Other Waters".

Versatility – quantification of heavy metals, organics and anions using the same instrument. The determination of organic additives in electroplating baths can be performed with optional accessories.

Speciation studies possible allowing statements to be made about the biological availability and toxicity of heavy metals making it an essential research tool for academia.

Calibration on every sample using standard addition eliminating many of the matrix effects seen in spectroscopic techniques and ensuring the correct result is reported.

Ability to determine samples with high ionic concentrations meaning the analysis of saline solutions, pure chemicals, electroplating baths and foodstuffs is no longer an analytical problem unlike with spectroscopic techniques.

Small footprint – less than a metre – requires no change to existing laboratory infrastructure or the installation of expensive fume extraction.

Quality Assurance – the PC software allows the validation intervals of the analysis system to be defined and comes with a built in software diagnosis.

Swiss quality guarantees performance and reliability plus that the comprehensive support expected from a World Leader of Ion Analysis for more than 60 years. 

And an even more important 11th reason, the price is currently less than £11,000 for the standalone instrument configuration (2.797.0010).
