MicroTrace™ OVA
The MicroTrace™ OVA7100 and OVA7100 Dual Cell are fully automated on-line metal monitors to provide continuous or intermittent monitoring of metals in process streams, effluent discharges, river and potable water.The OVA7100 and OVA7100 Dual Cell utilise internationally recognised voltammetry (ASV and CSV) technology, which provides quick and accurate determination of metals at the micrograms per litre (ppb) level, directly comparable with laboratory analysis using AAS or ICP.
They can provide real-time monitoring of several concurrent sample streams, configured to individual customer requirements. Sample pre-treatment may include digestion for elimination of potential interferences, although ASV is not affected by aluminium, sodium, calcium, magnesium, chlorine or other salts, often present in industrial samples which can cause problems with other analysis methods.Modern Water’s OVA7100 can be fitted with a variety of options for pre-treatment and sampling to enable accurate analysis of most types of water.
