3 Reasons to Call a Service Technician First
Contacting a Service Technician First Can Save Money, Decrease Downtime and Increase Productivity. Recently a client contacted us about needing another cadmium coil for nitrate analysis on their autoanalyzer. After checking their order history, we were puzzled to find that their cadmium coil was only a few months old. Digging deeper, we found that, oddly, [...]
Troubles with Cyanide Analysis? Call Technical Support First!
A Case for Laboratory Operators Using a Technical Support Contact as the First Step in Troubleshooting Many, if not most autoanalyzer and many other flow based instrument issues can be averted by operators utilizing a technical support contact at the very first sign of trouble. This recent case study clearly demonstrates the importance of why [...]
How to Test for Free Cyanide Utilizing Gas Diffusion
ASTM D7237 Standard Test Method for Free Cyanide with Flow Injection Analysis (FIA) Utilizing Gas Diffusion Separation and Amperometric Detection This is a new standard test method that was developed by ASTM Committee D19 to determine the concentration of free cyanide in an aqueous wastewater or effluents. The method detects free cyanide (HCN and CN-) and a [...]
Flanged Fittings Are Better Than Ferrules
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 [...]
The Benefits of Teflon Tubing for Autoanalyzers
Teflon Tubing Is a Powerful Tool for All Types of Laboratory Analysis Using an Autoanalyzer When Perstorp bought Alpkem way back when, they radically changed the platform and created the Expanded Range (ER) detector which to this day is arguably the best autoanalyzer detector ever made. In combination, they added their type of tubing and [...]
Utilizing Flow Injection Analysis and Gas Diffusion
ASTM D6888-09 Standard Test Method for Available Cyanide with Ligand Displacement and Flow Injection Analysis (FIA) Utilizing Gas Diffusion Separation and Amperometric Detection ASTM Committee D19 on Water has recently revised this standard. This method is used to determine the concentration of available inorganic cyanide in an aqueous wastewater or effluent. The method detects free [...]
