      How to Ensure Breathalyser Accuracy.

      Maria Pamboris

      Alcohol impaired drivers risk not only their own lives but the lives of others. They can face large fines, loss of license and even imprisonment. By removing these drivers, we reduce the potential for serious injury or fatal collisions on our roads.

      But how do we do that?

      SilcoNert® - Better performance, better results.

      Matt Shaw

      What is it?

      SilcoNert® is a non-reactive silicon coating process that makes flow paths inert for better process control, consistent sampling, and analytical results. The patented chemical vapor deposition process bonds the coating to stainless steel; alloy; ceramic; and glass, making a high-tolerance, durable coating even under extreme temperatures and pressures.

      SilcoNert® is made by SilcoTek Coatings, "the world's leading provider of high performance inert coatings applied by chemical vapor deposition (CVD)."

      Ozone for Water Treatment

      Greg Shires

      Ozone can be used for the treatment of water in multiple industries including municipal water treatment; wastewater; bottled water, wineries and breweries; aquaculture; drinking water for livestock; hydroponics; water treatment in cooling towers and air washers; public swimming pools; aquariums and zoos; commercial laundry facilities; soil/groundwater remediation and more.

      Ozone is typically generated using the electrical discharge method where oxygen is exposed to high voltage resulting in oxygen molecules colliding with O2 to create the unstable O3 molecules. 

      Ozone is 13 times more soluble than oxygen. This solubility makes ozone very useful in many water treatment applications. Ozone can be dissolved in water much easier than oxygen although it does still require mechanical mixing.

      Ozone is one of the most effective oxidants on earth, making it better than most chemical alternatives at breaking down contaminates and killing bacteria.

      Calibration Gas Solutions for Measuring Nitrogen Dioxide (NO2)

      Greg Shires

      Nitrogen dioxide (NO2) is one of a group of highly reactive gases known as oxides of nitrogen or nitrogen oxides (NOx). Other nitrogen oxides include nitrous acid and nitric acid. NO2 is used as the indicator for the larger group of nitrogen oxides.

      What makes a good calibration gas?

      Alex Singer

      There are two types of measurements made when preparing gas mixtures. The first is measuring what goes into the cylinder (volumetric or gravimetric measurement), and the second is measuring what comes out of the cylinder (measurement based on analysis). The first is relatively simple, as you need to only have:

      Disposal and Recycling of Gas Cylinders

      Paul Fry

      Recycling gas cylinderOnce you’re done with your calibration gas cylinder it’s important to safely dispose of it. All CAC GAS cylinders can be returned to us for proper disposal. Some can be reused, others cannot. No cylinders should be put into general waste and it can be difficult to find a recycler who will accept cylinders.
