17 Environmental Analysis & Electrochemistry SPE cartridges streamline PFAS testing
Resprep PFAS SPE cartridges offer a convenient, all-in-one solution for efficient sample preparation in PFAS analysis. Designed for complex matrices, these factory-packed cartridges combine polymeric WAX and ultra-clean CarboPrep Plus carbon sorbents, enhancing workflow efficiency in busy testing labs.
Each batch of WAX material undergoes rigorous testing for all 40 PFAS compounds listed in EPA Method 1633, ensuring reliable detection at required limits. The integrated carbon bed delivers effective cleanup, while an optional filter aid minimises clogging - reducing reruns and improving sample consistency compared to manually packed glass wool.

Spectroelectrochemistry: shedding light on the unknown
Spectroelectrochemistry is a combination of spectroscopy and electrochemistry. This hybrid technology possesses the advantages of each technique and can record an optical and electrochemical signal simultaneously.
Spectroelectrochemistry allows researchers to collect molecular, kinetic, and thermodynamic information from reactants, intermediates, and any products involved in electron transfer process. It’s therefore possible to perform spectroelectrochemical studies on a broad range of molecules and different processes including biological complexes, polymerisation reactions, and more.
Traditionally, the configuration for spectroelectrochemical analysis consists of two instruments: one spectroscopic instrument and one for electrochemical analysis. Both instruments are connected independently to the same spectroelectrochemical cell and are usually not synchronised. Each instrument is also controlled by a different software, so two programs are needed to interpret each signal and then a further external software is needed to process and analyse the data obtained. Additionally, because synchronisation isn’t guaranteed, tests with this configuration are slow, complex, and costly.
Metrohm DropSens created something that did not exist before - a revolution in spectroelectrochemistry; the SPELEC line of instruments are fully integrated, synchronised solutions that offer more versatility to researchers. The devices include all components needed to work with spectroelectrochemical techniques in a simple, single system.

ilmt.co/PL/YQAB 63732pr@reply-direct.com ADVERTORIAL A cost-effective solution for precision water quality control
Myron L® Company’s 900 Series multi-parameter water quality monitor/controller is easy to install, easy to use, and does the job of seven separate instruments single-handedly.
Precisely monitor and control an array of critical water and wastewater parameters with the legendary accuracy and reliability the Myron L Company has come to be known for. The 900 Series Monitor/Controller features a simple-to-use LCD touchscreen Graphical User Interface along with pluggable terminal blocks for quick and easy equipment installation and confi guration.
Get a comprehensive real-time picture of solution status with continuous readings from up to seven different inputs: 2 Conductivity/Resistivity/TDS/ Salinity; 1 pre-amplifi ed pH/ORP; 1 BNC pH/ORP; 1 fl exible 0-20/4-20 mA; 1 RTD Temperature; and 1 Flow/Pulse. % Rejection is also available as a derived value. For maximum accuracy, the Conductivity and TDS functions allow you to select the solution type used to model the solution under test: KCl, NaCl, or Myron L’s own 442 Natural Water™ Standard. Or program a ‘User’ solution mode based on a known solution. Temperature compensation is automatic to 25°C but can be disabled by the user as required. The pH/ORP input channel works with Myron L pre-amplifi ed pH and ORP sensors which contain precision circuitry that increases accuracy and permits application of the sensors over greater distances. The 0-20/4- 20 mA input allows user-defi ned 0 to full scale values and units of measure for a wide variety of sensor types. Electronic or wet calibrations are easy to perform.
Automatically trigger control equipment and audible signals and continuously report and record solution data with fl exible outputs. The 900 features up to 3 relays; 2 remote alarms; 1 0-20/4-20 mA signal; 1 0-5/0-10 VDC signal; and 1 RS-485 ASCII serial signal. Relays output to any user-supplied control equipment requiring up to 250V each and can trigger on any input parameter. The 0-20/4-20 mA output can transmit a signal for 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.
Myron L also backs these instruments up with expert dedicated technical support that assures installation and operation success.
