CHEMETRICS ANNOUNCES MOLYBDATE WATER ANALYSIS PRODUCT LINE
1-Minute Test Simplifies Molybdate Analysis for Cooling Water Treatment Specialists

These simple-to-use tests employ the catechol chemistry method and come packaged in CHEMetrics' patented technology-the self-filling ampoule.  This testing line was developed specifically with water treatment specialists in mind.  The design of the kit offers the analyst a rugged, accurate, nearly instantaneous on-site test for Molybdate in cooling tower water.  According to CHEMetrics, Inc.'s President and CEO, Gordon A. Rampy, "The development of this kit is a direct response to feedback from cooling water technicians world wide.  They asked us for an improvement over existing methods, and we've delivered with a one-minute, snap and read testing system."  The Molybdate Test Kits are available for both visual and instrumental readout, and cover treatment ranges for both open-  and closed-loop cooling systems.

Each ampoule contains a unit dose of liquid reagent sealed under vacuum, eliminating the need to measure and mix chemicals, simplying testing, and virtually preventing reagent spoilage.  To perform a test, the user snaps off the tip of an ampoule below the surface of the sample.  When the tip is broken, the sample is automatically drawn into the ampoule, where in a mildly reducing alkaline solution, catechol reacts with hexavalent molybdenum to form a yellow-orange colored chelate in direct proportion to the hexavalent molybdenum concentration.  Test results are expressed in ppm (mg/L) molybdenum; testing time is approximately one minute!
 

Molybdate is widely used in industrial water treatment and power generation industries as a corrosion inhibitor in both open- and closed-loop cooling water systems.  Molybdate is considered an effective, environmentally acceptable alternative to chromate treatment.  Unlike many other transition elements, molybdenum exhibits low or even negligible toxicity.

AFFORDABLE, PORTABLE METER FOR MOLYBDATE ANALYSIS
ONE-MINUTE TEST USES PATENTED SELF-FILLING AMPOULES

CHEMetrics, Inc. announces the availability of a rugged field instrument for the determination of molybdate in process waters.  The Molybdate Single-Analyte Meter reads CHEMetrics' patented Vacu-vials® ampoules, and unlike competitive meters, offers the analyst an accurate, nearly instantaneous colorimetric test for Molybdate in both open and closed-loop cooling systems.

The instrument uses an LED as a light source and features a long-lasting silicon photodetector.  Vacu-vials® ampoules contain a unit dose of liquid reagent sealed under vacuum.  The user snaps off the tip of an ampoule below the surface of the sample.  This causes a correct volume of sample to be automatically drawn inside the ampoule, where it reacts with the reagent to form a yellow-orange color.  The user then inserts the ampoule into the SAM, and results are displayed in parts-per-million (ppm) molybdenum.  Testing range is 0-30 ppm, with a Method Detection Limit (MDL) of 0.9 ppm.  The test procedure from start to completion takes one minute.

NEW MOLYBDATE MODULE FOR VVR WATER ANALYSIS SYSTEM

Calverton, VA )-CHEMetrics, Inc. today announced the availability of a new Molybdate module for its fast, accurate Vacu-vials® Reader (VVR) Photometer.  CHEMetrics' VVR reads CHEMetrics' patented Vacu-ials® ampoules, and unlike competitive meters, offers the analyst an accurate, nearly instantaneous colorimetric test for Molybdate in both open and closed-loop cooling systems.

The VVR uses a stabilized tungsten lamp as a light source; photometric accuracy is better than 1%.  Vacu-vials® ampoules contain a unit dose of liquid reagent sealed under vacuum.  To begin the test procedure, the user inserts the Molybdate Filter into the VVR Photometer and inserts the zeroing blank, which turns the instrument on and selects the molybdate calibration.  The user then snaps off the tip of a Vacu-vials® ampoule below the surface of the sample.  This causes a correct volume of sample to be automatically drawn inside the ampoule, where it reacts with the reagent to form a yellow-orange color.

After the instrument has been zeroed, the user inserts the sample-filled ampoule into the VVR; results are displayed in parts-per-million (ppm) molybdenum.  Testing range is 0-30 ppm, with a Method Detection Limit (MDL) of 0.9 ppm.  The test procedure from start to completion takes approximately one minute.

NEW PORTABLE INSTRUMENT FOR RAPID PERACETIC ACID ANALYSIS

CHEMetrics, Inc. announces the availability of a rugged hand-held instrument for the determination of peracetic acid in food & beverage and pulp & paper facilities.  Unlike competitive meters, the Peracetic Acid Single-Analyte Meter (SAM) reads CHEMetrics' patented Vacu-vials® ampoules and offers the analyst an accurate, nearly instantaneous colorimetric test for Peracetic Acid.

The instrument uses an LED as a light source and features a long-lasting silicon photodetector.  Vacu-vials® ampoules contain a unit dose of liquid reagent sealed under vacuum.  To perform a test, the sample is treated with an excess of potassium iodide-peracetic acid, if present, oxidizes the iodide to iodine.  The user snaps off the tip of an ampoule below the surface of the sample.  When the tip is broken, the sample is automatically drawn into the ampoule, where the iodine then oxidizes DDPD, a methyl-substituted form of DPD (N,N-diethyl-p-phenylenediamine) to form a purple-colored species.  The user then inserts the ampoule into the SAM, and results are displayed in parts-per-million (ppm) peracetic acid.  Testing range is 0-4 ppm, with a Method Detection Limit (MDL) of 0.08 ppm.  The procedure takes just one minute from start to finish!

Peracetic Acid is used widely in the Food & Beverage Industry as a sanitizing agent.  It is used to disinfect equipment, pasteurizers, tanks, pipelines, evaporators, fillers, and contact surfaces in food processing plants, dairies, breweries, and wineries.  The Pulp & Paper Industry uses peracetic acid as a delignification and bleaching agent.
