The Sievers M9 total organic carbon (TOC) analyzer measures TOC in a broad range of samples, from ultrapure water to process water. The analyzer can measure conductivity in grab sample or auto sampler modes, and produces TOC results in two minutes. The analyzer is offered in three versions—portable, online or laboratory—and is available worldwide, meeting all relevant global regulatory requirements.
The SAM-1 Smart Aqua Meter turns smartphones and tablets into pH, ORP or conductivity and temperature meters. Connect the meter and smart sensor into the audio jack of a smartphone or tablet and it is ready to take accurate readings. The sensor type and calibration data are auto-recognized. Easily record reading details such as time, date and GPS coordinates with location names and comments. Measure samples in the lab, field or plant, and share readings instantly via e-mail.
At only 18 sq in., the vario TOC Cube analyzer handles a wide range of samples, from ultrapure water to sludge. With large-diameter sample tubes — 0.8 mm — it easily handles somewhat turbid samples. The automatic liquid carousel can be swapped with a fully automatic solids carousel for samples with larger particles. An ash crucible protects the catalyst tube from plugging, allowing up to 3,000 samples to be analyzed without a reagent change.
The YSI Pro1030 handheld meter measures pH or ORP, plus temperature, conductivity, specific conductance, salinity and TDS. It has user-replaceable pH and ORP sensors, cables and a convenient calibration. Its ruggedness is backed up by military-spec connectors, IP67 waterproof and rubber over-molded case, and 1-meter drop tests. A four-electrode conductivity cell is built into the cable and requires minimal maintenance.
Before doing any testing, the best thing you can do is talk with your customer. Find out as much as you can about their water source, usage, aesthetic issues and family concerns. All of these factors will play into what you may test the water for in order to fully treat it. The source of the water will give you clues as to which contaminants may be present. For example, groundwater typically contains more minerals than surface water.
Considering customer needs and wants for water quality
Does your laboratory have an “ethical muscle?” Do you feel your employees are flexing this muscle? Ethics and data integrity should be an integral part of your laboratory’s quality assurance program. Just as peanut butter and jelly or milk and cookies go together, so do ethics, data integrity and quality. It is a logical concept, but it can be easy to overlook.
We are soon embarking on a new year. Make it your laboratory’s resolution to bring the topics of ethics and data integrity to a whole new level.
Strong Work Ethic
Maintaining ethics and data integrity in a laboratory setting
This multi-parameter test strip for drinking water tests free chlorine, total chlorine, pH, hardness, nitrate and nitrite with a single dip in less than 45 seconds. The strip, order code 2933-G, is appropriate for both municipal and well water applications. Each vial contains 25 test strips and is packaged in LaMotte’s exclusive flip-top vial with integrated desiccant liner and waterproof full-color chart on the label.
Approximately 30 million Americans get their drinking water from private household wells. Protection of private wells does not fall under the U.S. Environmental Protection Agency’s (EPA) Safe Drinking Water Act, so well owners must take it upon themselves to ensure their water quality. To keep water clean and pure and the well operating at peak performance, regular water testing is an important maintenance tool.
Selecting the right combination of tests for water wells
The TRM-1 is a wide-range TDS monitor, able to measure 0 to 10,000 ppm with three different sensors. It is ideal for water filtration/purification systems that require three sensing points, such as RO/DI systems. Each sensor is ¼ in. in diameter. The monitor comes with three ¼-in. quick-connect T-fittings. It is battery powered, has automatic shutoff, automatic temperature compensation and an accuracy of ±2% (of the reading).
Analytical Measurements manufactures probes for use with pH and ORP instrumentation, as well as resistance temperature detectors for use with automatic temperature compensating controllers/recorders. All probes work with many instrument manufacturers, as long as a BNC-type connection is used. The company offers standard industrial probes, as well as higher temperature/pressure, flat surface, spear type and cyanide probes.
