Determination Of EN15662:2008 - Determination Of Pesticide Residue In Food Of Plant Origin, By An Automated QuEChERS Solution
9/24/2014
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.

Immediate pH Correction For Fluctuating Flow
2/19/2014
In a number of water, wastewater and industrial process applications, pH is one of the most critical and highly sensitive analytical measurements. Examples of critical pH applications include: Reverse Osmosis (RO) systems in which a controlled feed of caustic solution is typically added to the feed stream in order to convert a portion of dissolved carbon dioxide into bicarbonate precipitate allowing for removal by the RO membrane.

ABB Aztec 600 Manganese Analyzer Optimizing Manganese Removal Efficiency
11/15/2017
The task of managing the quantity and quality of potable water is unimaginable without online instrumentation to help water utilities to measure, treat and deliver drinking water to consumers. ABB’s Aztec 600 colorimetric and ion-selective electrode (ISE) analyzers have been designed to measure the key parameters that affect water quality – aluminium, iron, manganese, phosphate, color, ammonia and fluoride.

Circuit Board Cleanliness Testing
10/29/2021
Contamination of circuit boards can bring about severe degradation of insulation resistance and dielectric strength. Cleanliness of completed circuit boards is, therefore, of vital interest. For those companies who have established circuit board cleaning procedures, the MIL Spec P-28809 has been used as a guideline for control. Now a simple "on line" test for the relative measurement of ionic contamination has been developed.

Why Should We Care About NSF/ANSI 61 Certification?
3/17/2021
According to National Sanitation Foundation (NSF) and the American National Standards Institute (ANSI), it's a set of standards relating to water treatment and establishes criteria for the control of equipment that comes in contact with either potable water or products that support the production of water.

Removal Of PFCs With Activated Carbon
12/30/2013
In recent years, various perflorinated chemicals (PFCs) have come under increasing scrutiny due to their presence in the environment, in animals, and in human blood samples. There are two major classes of PFCs: perfluoroalkyl sulfonates such as perfluorooctanesulfonic acid (PFOS) and long chain perfluoroalkyl carboxylates such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA).

Validation Of Environmental Water Methods On One System
4/6/2015
Water quality laboratories across the nation are faced with both a rising level of water quality awareness amongst the general public, as well as rising costs in water quality monitoring. As a result, laboratories are looking for more efficient ways to provide higher quality monitoring.

All WirelessHART Devices Are Not Created Equal
12/4/2015
Though they all must support routing functionality, some devices do it better than others.
Routing consumes more energy, so the lifetime of the battery will be affected. Therefore, a device with a battery that is inexpensive, has a long lifetime, and is easy to change would be ideal. With all this considered, a WirelessHART temperature transmitter is a suitable option to operate as a repeater.
