What is a Permeation System?
A permeation system is a simple yet effective device used to generate precise gas blends for a wide range of applications, from biological/medical mixing to sensor calibration. Users typically opt for permeation if they require gas mixtures with low-level concentrations, or if their gases are not readily available in bulk formats. Permeation ovens subsequently tend to be custom systems designed ...

Online Total Bacteria Monitor compared with ATP and Flow Cytometry
Alkaline Phosphatase Enzyme Activity Measurement as a Robust on-line Monitoring Assay for Water Quality Assessment. Micro organisms maintain their growth by producing enzymes in order to provide low molecular weight inorganic compounds. These compounds could be taken up into the cells from high molecular weight organic compounds which cannot be directly utilized by bacteria. Microbial enzymes ...

Detecting industrial discharge events - Case Study
Periodic foaming in an aerated digester and a drop in dissolved oxygen were affecting the performance of the Montague Wastewater Treatment Facility in Three Rivers, Prince Edward Island. "We knew something was upsetting the biology, hut not what it was because the digester returned to normal in a day or two," says Tommy MacLeod, operator. "The situation was exacerbated by our dewatering problems. ...

Exxon Valdez Tanker Spill - Case Study
In 1989 the world’s first big oil tanker disaster occured off the coast of Alaska. The Exxon Valdez’s oil cargo polluted the pristine coast line of Alaska. Exxon searched the globe for a biotechnological solution to the Valdez spill. French Petroleum company ELF AQUITAINE was developing a bio-remediation product called INIPOL EAP-22. After extensive tests Exxon purchased ...

Nitrate Biosensor - Case Study
BACKGROUND In 1998, Dr. Bill Campbell and his team published a peer-reviewed journal article in Analytical Chemistry on the construction and characterization of Nitrate Reductase-Based Amperometric Electrode and Nitrate Assay of Fertilizers and Drinking Water. This publication set the stage for the nitrate biosensor project. In this publication, we found that nitrate reductase was indeed capable ...

CVD Diamond
We have cvd diamonds for sale! CVD (Chemical Vapor Deposition) diamond. The mixture of carbon-containing gas and oxygen is excited and decomposed at a high temperature and a pressure lower than the standard atmospheric pressure to form an active diamond carbon atom, and the deposit is alternately grown on the substrate to form a polycrystalline diamond. The high hardness and high wear ...
