With the continued use of conventional microwave vessels, the vessel and sub components quality, will progressively degrade with aggressive acid attack and need to be replaced. TFM-PTFE has demonstrated a superior resistance to strong acid attack allowing aging...
What is Microwave Digestion?
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...
Overcoming BioFouling
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...
Particle Counters: Single Optical Particle Sizing
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...
Measuring Deep Sea currents
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....
Fast Optical Dissolved Oxygen Meter
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...
Camera viewing of SFE
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...
