Origin: Germany Model: SCH4000 SCH4000 evaporative light scattering detector main parameters: evaporative light scattering detector SCH4000ELSD is universal HPLC detector, which can be used to analyze those without UV absorption, difficult to separate the solvent, or you must use a gradient elution You can not use a differential detector samples. ELSD has a limitation is not contained within the mobile phase buffer. Compared with other vendors ELSD, SCH4000 have included a nebulizer and an evaporator consisting of a rotating glass chamber. The rotating chamber for easy removal from the instrument down and cleaned. Procedure Introduction: phase flow containing component to be measured is atomized into an aerosol and at a given angle is injected into the whirling chamber, in this process, a large and a small presence of a selective aerosols, aerosols along large the wall flow of the waste outlet and small aerosol carrier gas is heated to carry and rotational motion, aerosols are dry. The amount of the carrier gas may affect the length of the drying time of aerosols by the flow controller. The latest technology (patent) such that the aerosol process optimization, so the work can be carried out at a relatively low temperature mode. Instrument parameters: Source: Tungsten halogen lamp Detector: photomultiplier Temperature range: --- 70 ℃ atomization carrier gas flow rate: <1M / min additional spin drying gas flow rate: less than 2M / min carrier gas flow control: via built controller to control additional drying gas, electronic pressure controller atomizing gas flow rate output: analog output 0-5V, RS-232 input: Start, back to zero power-saving mode: carrier gas, lights, heating, photomultiplier tube closure error Mode: airflow, heating, lamp failure, photomultiplier tube failure instrument control: Keyboard, RS232 Display: LCD power four lines: 100V / 60Hz-220V / 50Hz Appearance: 27 × 50 × 47cm (w × h × d) Weight: 18Kg SCH4000 evaporative light scattering detector advantages: 1. spiral technique, effectively increases the length of the longer the evaporation tube evaporation tube, the lower the required evaporation temperature, the mobile phase is evaporated to give the more complete, baseline noise also. The lower, so SCH4000 got better baseline, higher sensitivity, lower detection limits. 2.SCH4000 optical detection system for a halogen lamp + photomultiplier tube can very weak current amplification, detection sensitivity is improved. 3.SCH4000 without split injection, which can detect samples containing semi-volatile, thermally unstable and stable components, ensure that all components of the sensitivity and detection limits. 4.SCH4000 cryogenic type of evaporative light scattering, more stable baseline, higher sensitivity.
