The D3270 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 delivers stable baselines even under multi-solvent gradient conditions, ensuring high resolution and fast separations. The detector incorporates a 30 mW, 650 nm high-stability Class 1 laser and a high-sensitivity photomultiplier tube, providing 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, comprehensive alarms for temperature, flow, and pressure, and UDP-based communication, enabling safe and unattended operation.
