To measure the quantity of a metal in a sample, the metal must first be dissolved completely into a solution (called an analyte) before it can be analysed using AA (atomic absorption) or ICP Inductively Coupled Plasma. For semi quantitative analysis, hot plate...
This presents the greatest challenge for environmental scientists trying to measure long term parameter trends in warm shallow oceans such as Australia. In cooler water masses, instruments are able to be used in conjunction with copper foil and anti-fungicides such as...
The history of particle counting can be traced back to the 1950’s when Wallace Coulter, an American electrical engineer and inventor discovered a method to count microscopic particles suspended in a fluid. Coulter found that individual particles moving through...
Traditional ocean-current measurement uses doppler instrumentation that works well in shallow turbid columns. At depths lower than 1,000 metres, water masses are devoid of particulate matter making it difficult for doppler instruments to gather sufficient deflections....
Galvanic electrode dissolved oxygen (DO) sensors have been developed for several decades but have had been problematic in the field because they have slow response times, typically 25-50 seconds and measuring DO at baseline levels is not very accurate. The Rinko is a...
Normally the Supercritical Fluid Extraction process is conducted in thick walled vessels that do not allow observation while processing. Applied Separations now have designed a viewing port that can be installed in any of their vessels. A special camera can be...
For tanker discharge, the WaterSam AutoSam provides a complete automated discharge and sampling system. The system comprises: Driver Card reader & identification. Fluidics connections, mag flow meter,conductivity/pH sensors. Autosampler to take...
For field applications, the WIZ probe is able to measure up to 4 analytes in a water column. Detection limits are down to low ppb for all typical reported compounds and deployment can be for up to 1 month unattended. Reliable methods are used for NH4 (fluorimetric)...
Using the Single Particle Optical Sizing (SPOS) technique, the accusizer is able to provide particle size distributions as particles versus size or any other distributions eg. such as volume % vs size etc. Importantly the total particle concentration can be shown or...
The Micromac unit is designed for industrial and environmental applications. It can be custom designed to meet the most challenging low levels encountered in environmental deployments,including TOC in sea water, to robust units that can work in tanneries. The analyzer...
