This ICP-OES analyzer is now twice as sensitive

Spectro Analytical Instruments

The new Spectrogreen inductively coupled plasma, optical-emission spectrometry (ICP-OES) analyzer (photo) features a revolutionary Dual Side-On Interface (DSOI) technology that achieves twice the sensitivity of conventional radial-plasma-view instruments, at an attractive price/performance ratio. DSOI technology, a brand-new approach to the critical issue of plasma view design, uses a vertical plasma torch, observed via a new direct radial-view technology. Two optical interfaces capture emitted light from both sides of the plasma, using only a single extra reflection, for added sensitivity and elimination of issues that plague newer vertical-torch dual-view models. As a result, DSOI provides twice the sensitivity of conventional radial systems and yet avoids the complexity, drawbacks and cost of vertical dual-view models. — Spectro Analytical Instruments GmbH, Kleve, Germany



A cyanide analyzer for industrial wastewater

Electro-Chemical Devices

The S80-T80 cyanide analyzer monitoring system (photo) features an S80 Pion Cyanide Sensor and a dual-channel T80 Transmitter. The cyanide analyzer helps plants achieve a more cost-effective cyanide-removal water-treatment system, which ensures wastewater is treated to meet U.S. Environmental Protection Agency (EPA) regulatory requirements prior to effluent discharge. The S80’s CN-ion electrode is a combination electrode with a silver cyanide/silver sulfide solid-state pressed-crystal sensing element and a double junction reference electrode. The CN-ion selective electrode cartridge develops a millivolt potential proportional to the concentration of free CN ions in the measured solution. The typical output is 54–60 mV per decade of change in concentration. The sensor’s response time varies from a few seconds in concentrated solutions up to a few minutes in the lower parts per million (ppm) range. This analyzer measures CN from 0.2 to 260 ppm. — Electro-Chemical Devices (ECD), Anaheim, Calif.



Limit-value display simplifies process monitoring


LiquiSonic systems (photo) measure concentration and density in process liquids by sonic velocity. In addition to displaying the numeric concentration, density and temperature, the LiquiSonic now also displays the limit-value ranges, which simplifies the monitoring of an approximation of critical values. Users can identify the segment in the measuring range where the current value is settled on and get a quick overview. The LiquiSonic controller display allows up to three value ranges at the same time. This applies for each one of the up to four sensors, which can be connected to a control unit. — SensoTech GmbH, Magdeburg–Barleben, Germany

A transmitter for analytical sensors where space is limited


The Liquiline compact CM82 transmitter (photo, p. 26) accepts pH, ORP, pH/ORP, conductivity, oxygen and chlorine sensor signals from this company’s Memosens sensor platform. Its housing is only 11 cm long and 2 cm wide, so even combined with the sensor, it fits into almost every assembly, says the company. Although small, it is a fully developed multiparameter transmitter, with access available via 4–20-mA HART, or Bluetooth from any iOS or Android device. The CM82 reads all sensor and calibration data stored in the head of a Memosens sensor. As a result, the sensor is automatically detected within seconds, and the measurement is immediately ready for use after a sensor change. — Endress+Hauser, Greenwood, Ind.

A cross-pipe version of this TDL gas analyzer

With most tunable diode laser (TDL) gas analyzers, loss of alignment leading to loss of measurement signal during a running process can be a constant problem. The Cross-Pipe GPro 500 analyzer means maintaining alignment is no longer an issue. The GPro 500 series of TDLs solves the alignment issue by combining both the source and the sensor into a single unit. A probe attached to the sensor features a corner cube at its end that redirects the laser beam back to the sensor; therefore, loss of alignment is not possible. The probe concept is highly reliable in stacks with a diameter of less than 1 m. For wider stacks, where gas concentration is not constant, the company has introduced the Cross-Pipe GPro 500, thereby extending the application coverage of its GPro 500 family. A newly developed, two-dimensional corner cube array is positioned in the pipe, opposite the analyzer head. Exact alignment is not required. — Mettler-Toledo Process Analytics, Inc., Bellerica, Mass.
