Eagle Microsystems’ RA-1000 is an amperometric-type, precision, low maintenance instrument for analysis and control of chlorine residual in the water and wastewater processes. The unit is capable of measuring free or total residual chlorine using inexpensive white vinegar as the buffering agent. Alternatively a CO2 buffering system is available. The analyzer is available with either a gravity or peristaltic pump-fed reagent system. The digital electronics provide flexible monitoring and control of either direct residual measurement, residual control or compound loop control.

Stormwater sampler

The I-Chem, available through Forestry Suppliers, collects a full one-liter sample of first flush storm water within the first 30 minutes of a rain event in compliance with EPA sampling requirements. A floating ball valve seals off the sample collection port to prevent co-mingling with run-off water as well as volatile analyte loss. Water flows through the sampler’s collection funnel directly into a Nalgene® sample bottle, so no sample transfer is necessary before transport to the lab. The sampler can be securely mounted in a storm water ditch, stream, or storm grate outfall.

Agar replacement

The patented Easygel agar replacement simplifies testing for coliforms and E. coli in environmental samples, drinking water or treated wastewater. Available through Forestry Suppliers, the pectin-gel testing method is sold as a sterile 2-part test unit consisting of a patented liquid medium and a pretreated petri dish. When the liquid medium is poured into the petri dish, ions diffuse from the pretreated layer into the liquid, causing it to gel in about 40 minutes. Easygel Coliscan samples up to 5 ml from environmental sources with high coliform or E. coli populations.

Waters Equipment’s Portable QC Cart allows on-line verification of analytical instruments throughout the plant. When used with a conditioned sample, the cart eliminates sampling problems such as contamination, delays and temperature as well as phase changes in the sample within the transfer tubing. The cart can be used to measure on-line specific or cation conductivity, dissolved oxygen, pH and TOC. The unit is constructed of high-purity 316SS and plastic wetted parts and requires very little maintenance.

TOC measurement

Rapid oxidation of gas samples for Total Organic Carbon (TOC) measurement can produce condensation which interferes with accurate readings. Perma Pure’s MDTM-Series and MDHTM-Series Dryers remove excess water vapor to keep TOC analyzers free from damage and inaccurate results. Using patented Nafion® membrane technology, the dryers selectively remove only water vapor from gas samples, leaving the carbon dioxide concentration intact for TOC measurement. With this one step drying solution there is no need for a drip leg, peltier cooler, or desiccant canister.

Water quality testing

IDEXX Laboratories has launched the Quanti-Disc® Reader for the Quanti-Disc® test, a new method for testing Total Viable Counts (TVC) in water. The method produces results that correlate with the International Standard ISO 6222 Yeast Extract Agar pour plate method incubated at 36° ± 2°C for two days or at 22°C ± 2°C for three days. The new reader further simplifies testing by increasing ease-of-use and accuracy. With automated reading and recording of results, the reader eliminates any subjective results interpretation and allows laboratories to read a high number of samples in a short amount of time. It also improves accuracy by enabling sample bar coding, recording and storage of test results, and integration into a laboratory information management system (LIMS).
