The EZkem blog is your go-to resource for laboratories in the spectroscopy fields — including flow analysis and cyanide analysis.
A Short History of the Gas Diffusion Module
Gas diffusion modules are used in autoanalyzers whether segmented flow analysis (SFA), sometimes referred to as continuous flow analysis (CFA), or flow injection analysis (FIA). The purpose of the gas diffusion module is to function as an in-line cleanup eliminating particulates, potential ionic interferences and chemical complexes. The target analyte permeates through the membrane into a [...]
Standard Curves and Check Standards Can Make All the Difference
Standard curves and check standards can make all the difference in the successful operation of autoanalyzers and discrete anlayzers. The importance of validating results for accuracy becomes a very important rock of consistency when operating an autoanalyzer or discrete analyzer in the hazardous field laboratory analysis environment. We are taught how to make standards and validate them with [...]
Autoanalyzer Troubleshooting Basics: Inspecting The Flow Cell
In this series of discussions, I wanted to address specific problem areas that laboratories encounter while operating auto analyzers. These segments will each focus on the individual items that EZkem repairs, replaces, reconditions or in any way modifies while doing service in the field or in our repair facility, like inspecting the flow cell. Initially, I would [...]
Poor Reproducibility? 3 Reasons Your Peristaltic Pump Could Be The Problem!
The peristaltic pump is a very important component in the proper operation of an autoanalyzer instrument. If it is not functioning properly, it’s possible to have problems with reproducibility, accuracy, and prematurely worn pump tubing. These signs of a pump problem might be observed as poor peak shape, split peaks, tailing peaks, surging, and inconsistent [...]
Welcome to EZkem
I specifically remember my first day as a chemist with the FDA and not just because it was the first time I was expected to wear a tie to work. After leaving college, and a challenging, but predictable laboratory experience, I stepped into an extremely complicated, fast paced lab, an alternate reality where instead viewing [...]
Autoanalyzer Debubblers Need to Be Replaced
There are many reasons why people use auto analyzers and it's much less expensive and more profitable to keep an older autoanalyzer running as long as possible instead of spending the money for a costly replacement. If a lab does choose to run an older piece of equipment, it is imperative that they spend a [...]
