New Handheld Optical Oxygen Sensor
The new NeoFox Phase Measurement system from OceanOptics (Netherlands) is a fluorescence-based optical sensor system that helps you reduce costs, improve stability and make calibration easier for a wide variety of oxygen sensing setups. NeoFox is the benchtop device for measurement of fluorescence lifetime, phase and intensity and is particularly suited for applications where sensitivity to drift and system stability are critical.
Additionally, NeoFox is now available in a new Sport version. NeoFox Sport is the portable, handheld, system that includes the NeoFox phase measurement system with LED light source, rechargeable battery pack and low- power display.

New Web Tool Creates SPE Methods in Seconds
Phenomenex (USA) introduces the Solid Phase Extraction (SPE) Method Development Tool - a fast online resource. This tool develops methods across a variety of sample matrices and compounds, enabling users to improve analyte concentration and detector response. The researcher enters the name of the analytical target or selects "proprietary" to develop a method based on the chemical characteristics of the analyte.
"The use of SPE is on the rise in many industries because cleaner samples increase column life and provide increased sensitivity with fewer interferences," explains Erica Pike, brand manager for Phenomenex. "Researchers are continually developing new and revised methods, and we have already developed more than 700 using this tool."

EK-P3, the new evaluation kit from Sensirion (Switzerland), represents a straightforward and costeffective option for testing the digital differential pressure sensors of the SDP600 series. The set consists of a USB stick that is connected to the SDP610 sensor by an adapter cable. With the help of the software, which is available online for download, the differential pressure sensor can be tested under realistic conditions by following five simple installation steps. Consequently, there is no need to program a microprocessor as the evaluation kit maybe connected directly to a PC. The included software allows displaying measured values on the screen and additionally provides the option of exporting the data to an Excel spreadsheet. This enables the data to be saved and processed in a simple manner.
The differential pressure sensors of the SDP600 family, have a digital (I2C) output signal, are extremely stable and impress with their accuracy and sensitivity, even at very low differential pressure values. The high performance is reached due to the thermal flow through principle. Thanks to the new EK-P3, the customer can learn more about the differential pressure sensor, become convinced of the benefits it provides and experience these clear advantages in a highly time efficient and economical manner.
