Pesticide residue laboratories are required to undertake analyses of an ever increasing number of samples. The analyses typically involve use of multi-residue methods (both GC-MS and LC-MS) to test for over 500 pesticide residues.
Hot Clean-In-Place (CIP) sanitization is commonly used to combat microbial growth in the pharmaceutical and food and beverage industries. Performed frequently as a prevention strategy, hot water sanitization is a requirement for high purity water (HPW) for United States Pharmacopeia (USP) and European Pharmacopoeia (Ph. Eur.).
A static headspace method was developed using Teledyne Tekmar automated headspace vial samplers to meet the method requirements of the Alcohol and Tobacco Tax and Trade Bureau of the US Department of the Treasury (TTB) method SSD: TM:2001 for testing fusel alcohols in alcoholic beverages.
Rising energy prices have made accurate energy measurement a hot topic in recent decades. The need for accurate measurement technologies extends to many different application areas, including heating and cooling; compressed air; steam production and distribution; heavy fuel oil consumption; energy monitoring; and custody transfer. In response, new technology is being developed that integrates tasks previously requiring several measurement devices.
As interest in biogas grows, more attention is being paid to measuring biogas flow, which has long been a problem area in process measuring technology.
Increased gas content often leads to problems with bubble formation in highly viscous fluids. 3M™ Liqui-Cel™ Membrane Contactors can provide a simple, compact, and efficient in-line solution for removing bubbles from viscous liquids before they create problems in a process operation.
The C445 motor management relay offers the most configurable protection options in the industry, with features specifically designed to protect critical pumps from costly damages due to dead-head and other underloaded or starved pump conditions.
There are several basic methods for reducing harmonic voltage and current distortion from nonlinear distribution loads such as adjustable frequency drives (AFDs). Following is a description of each method, along with each method’s advantages and disadvantages.
