The D3270L Evaporative Light Scattering Detector (ELSD) is a universal mass-sensitive detector that does not rely on the optical properties of the analyte, making it ideal for compounds lacking chromophores or fluorescent groups. It operates through three well-defined stages—atomization, evaporation, and detection—and delivers stable baselines even under multi-solvent gradient conditions. The detector incorporates a 30 mW, 650 nm high-stability Class 1 laser and a high-sensitivity photomultiplier tube, ensuring excellent sensitivity and reproducibility. Flexible parameter control is available via a handheld controller or fully integrated Kromstation software, allowing adjustment of evaporation temperature, carrier gas flow, nozzle heating, sensitivity, signal bias, output range, sampling frequency, and digital filtering. Up to ten complete methods can be stored and recalled. Intelligent features include automatic power-on self-test, leak alarm, TCP communication, and comprehensive alarm settings for temperature, flow, and pressure, ensuring safe and unattended operation.
