Carbon and Sulphur Analysis Made Easy


For the safe, precise and reliable elemental analysis of carbon (C) and sulphur (S) in predominantly organic matrices such as soils, waste, wood, oil, coal and coke, Eltra’s new combustion analyser ELEMENTRAC CS-r with IR detection is the perfect choice.


The CS-r with up to 4 infrared cells is designed for carbon and sulphur measurement over a very wide concentration range. It uses a horizontal resistance furnace with ceramic tube, which operates in a range from 600°C to 1550°C. The CS-r elemental analyser meets or exceeds the requirements of all common ASTM, DIN, EN or ISO standards for elemental analysis.


A high sample weight of up to 500 mg ensures excellent reproducibility of the elemental analysis results, even for heterogeneous samples.


The high combustion temperatures and electronic monitoring of the oxygen flow allow complete oxidation of the sample and help to avoid too low results even with challenging materials like cement. For optimum user convenience, a monitor holder can be attached to the analyser, operation is possible via touchscreen or keyboard. More information online: ilmt.co/PL/eYYw

Analysis of 8 Polychlorinated Biphenyls (PCB) in Environmental Matrices by GC-MS/MS


PCBs are resistant to decomposition in the environment, and tend to accumulate in living organisms. As a result, they are designated as POPs (Persistent Organic Pollutants). In monitoring these environmental pollutants in river water and sludge, sensitivity for the detection of trace quantities and separation from impurities in the samples become important issues. An application from Shimadzu demonstrates the analysis of 8 different PCB over a broad calibration range (0.1 μg/L to 200 μg/L). Instrument calibration was done using an internal standard approach. 8 levels between 0.1 μg/L and 200 μg/L have been measured for calibration and resulted in R2-value above 0.9995 for all compounds. Stability evaluation of the calibration was done using the internal standard (ISTD) stability. Each sample contained identical amount of ISTD spiked at the end of sample preparation. Excellent sensitivity combined with a high linear dynamic range was shown for standards and real world samples in PCB analysis using GCMSMS. Excellent sensitivity combined with a high

One Compact Instrument for all your Water Quality Management Needs


Whether in industrial, commercial or municipal locations, Myron L’s 900 Series Monitor/Controller provides a comprehensive solution to simplify water quality management in a single, compact instrument. This 1/4 DIN, user-intuitive instrument can simultaneously monitor 7 critical water quality parameters: 2 Conductivity/Resistivity/TDS/Salinity; 1 pre-amplified pH/ORP; 1 BNC pH/ORP; 1 0-20/4-20 mA; 1 RTD Temperature; and 1 Flow/Pulse. % Rejection is available as a derived value.


The 900 Series’ outputs include up to 3 relays; 2 remote alarms; 1 0-20/4-20 mA; 1 0-5/0-10 VDC; and 1 RS-485 ASCII Serial Output. Relays output to any user-supplied control equipment requiring up to 250V each and can trigger on any input parameter. 0-5/0-10 VDC can be scaled to optimise resolution and can output to a recorder, PLC, SCADA system, etc. 0-1 VDC is possible with optional resistor. The 0-20/4-20 mA output can transmit a signal for any input parameter.


A loss of flow condition will disable all relay outputs when a flow switch is installed and connected to the 900. 0-20/4-20 mA input allows user- defined 0 to full scale values and units of measure for a wide array of sensor types. User-specified hysteresis value prevents chatter or let the 900 Series automatically determine it for you.


Configuration is simple with easy-to-follow on-screen prompts; the brightly coloured red, yellow, or blue LCD background instantly alerts the user to the solution status. It is extremely simple to perform both electronic and wet calibrations. The Administrator and Operator password protection levels prevent unwanted tampering.


In addition, users can rely on Myron L’s first-class technical support for the instrument’s full lifetime. More information online: ilmt.co/PL/rAlK
