Analyser protection usually consists of a coalescing and/or a particulate type filter to remove liquids and solids. But what happens when the housing isn’t serviced and becomes flooded with liquid? The liquid will carry over and reach the sensitive (and expensive!) analyser – we have discussed this on the blog before in this post System…
What is SilcoNert®? SilcoNert® (formally called Sulfinert®) from SilkoTek® gives the ultimate passivation treatment of stainless steel surfaces. Filter elements and housings can adsorb active components in sample streams and the surface area of stainless steel filters can increase sample contact by a large amount. This is not a consideration with our disposable filter media as these offer…
