This blog will detail the proper maintenance of Gas diffusion membranes. There are various approaches, some labs replace their membrane daily preferring to avoid the issue altogether while others may go weeks or even months using one membrane with no issues. So, what is the right approach? Unfortunately, there is no definitive answer as there [...]
These OI Analytical FS3700 heaters are quite robust as the electronics are all contained in the board of the system not in the heater itself, which limits points of failure. However, over time the tubing can degrade or become clogged, this means that often many issues can be completely resolved with a simple rewrap, using [...]
You can upgrade your Cetac Autosampler from a 500 or 510 model to the current ASX-520 model. EZkem has the ability to take your old Cetac 500 or 510 autosampler model and upgrade it to the current 520 model. The older models required specific processors for each platform. The nice thing about the 520 autosampler is that it [...]
Further Discussions Our last blog post about how much better Teflon is than glass resulted in extensive responses from many different users. Some users were in agreement, some were thankful for the facts regarding how much better the physical properties of Teflon are over glass and others were somewhat confused. The main confusion has to [...]
- And the Science behind It Years ago when I started working with autoanalyzers, glass was the most common material used to transport and mix fluids and I dutifully learned the art of working with very expensive and easily snapped fragile mixing coils and glass fittings. At the time I was told that glass had [...]
Containers Should Be Rinsed After Each Use From a service and support point of view, we often have difficulty getting operators to see that, on a daily basis, sometimes the small things can be as important as the big things. Operators easily see the value in replacing pump tubes, changing the lamp in the detector [...]
Flow Analyzer System Restoration and Innovation Have you ever found yourself staring at your flow analyzer wishing, that like a vintage automobile, it could be fully restored? Though SFA/FIA technology has actually changed very little over the last few decades, it is usually more cost effective to restore your existing equipment than to spend more [...]
There are several different types of materials used for mixing manifold cartridges in autoanalyzers. One of the two most common manifold materials utilized is clear acrylic which is often considered optimal due to its transparent quality giving greater visibility to the chemical reagents flowing inside the mixing tees. The other is polysulfone, a significantly darker [...]
Sometimes the small things are just as important as the major components on an autoanalyzer. When issues arise we focus on the pump tubes, the peristaltic pump or even the reagents themselves, but often operators overlook their containers. Containers hold, arguably, the most important part of the system; reagents, and are critical to the successful [...]
Flanged Fittings are Better Than Ferrules for Alpkem, Perstorp or OI Analytical Autoanalyzers Autoanalyzers vary by manufacturer on what type of fittings they use to secure tubing into the reaction manifold as well as the other various fittings on the system. Some just use sleeves where the tubing simply slides over a nipple or some [...]
