Approved Cyanide Determination Methods
Docket ID No. OW-2003-0070 Comments Related to the Proposed Cyanide Determination Methods Federal Register / Vol. 69, No. 66 / April 6, 2004 / Proposed Rules, pp. 18166 – 18226 Prepared by: Emil Milosavljevic, Ph.D. and Ljiljana Solujic, Ph.D. Distillation-based methods for determination of operationally defined cyanide have very limited application because of the serious interferences from the species likely [...]
Saint-Gobain Introduces Tygon S3™ non-DEHP, Phthalate-free Flexible Peristaltic Pump Tubing
By now, most of us have heard that we shouldn’t put plastic in the microwave, though many still do it without a thought. A quick search on the internet for phthalates turns up key phrases like endocrine disrupters and insulin resistance, baby bottles, water bottles and so on that all seem to be leading us [...]
Welcome to the New EZkem Blog!
We’re excited to announce the launch of our newly updated EZkem blog on our blog! We encourage you to bookmark our page or subscribe to our RSS feed. We are constantly dialoging with our clients about parts, repairs, reconditioned system builds and any questions they have to keep their lab running smoothly. Through our blog [...]
Used to help liquids flow through autoanalyzer tubing more easily and to help facilitate mixing, surfactant is a necessity for flow analyzers. Surfactant has been used since autoanalyzers were constructed and comes in many varieties, but I prefer basic Brij-35 and Dowfax 2A1. These two, tried and true surfactants were the mainstay for nearly all [...]
Flow Cells Need Maintenance
In this article, I am going to focus on flow cell maintenance. Keeping an older autoanalyzer running can save considerable amount of money for a lab, but this does not mean that its operation is free. If a lab takes a little time and money to keep up a few essential parts on an autoanalyzer [...]
Autoanalyzer Troubleshooting Basics: Inspecting the Debubbler
As solutions flow through an autoanalyzer system the debubbler is a key component in providing the opportunity to evaluate the condition of the reagents and ultimately the sample. It’s through the debubbler that we can see if the bubble patterns are correct, if there is a block in the cartridge causing surging, how well the [...]
