AS/MSD-007 Liquid Chromatograph@Hitachi High-Tech Science Corporationhttp：//www.hitachi-hitec-science.comC2015 Hitachi High-Tech Science Corporation Analysis of Disinfectant (Triclosan) by Mass Detector Chromaster 5610 MS Detector is a mass detector with new concept， designed for LC users， and itis different from conventional mass spectrometers. This time， the analysis example of triclosan isintroduced here. Triclosan is used as a disinfectant for general bacteria in wide range of productsincluding health care products such as medicated soap and toothpaste and plastic and fabricproducts such as children’s toys. No complex condition setting is required for 5610 MS Detectorand thus， mass information can be obtained and a calibration curve can be generated with theoperability equivalent to that for UV detectors. LC-MS Analysis of Triclosan Table2 Analytical Conditions for HPLC Column LaChromⅡ C18(1.9 um)3.0 mm l.D. x 100mm Mobilephase CH3OH Flow rate 0.3 mL/min (1：50 sprit) Column temperature 40°C Detection wavelength UV 286 nm Injection vol. 10pL LC-MS Analysis Triclosan was dissolved in methanol. In the mass spectrum， [M+H]"ion peak was detected at m/z 288.6 (Figure 2).Figure 1 shows the results from the analyses of triclosan (10 ng/mL) by UV and mass detectors. In a conventionalHPLC system， the flow channel is split for the connection with a mass detector. In the SIM chromatogram oftriclosan， the sensitivity was found to be equivalent to that obtained by UV detection. The calibration curve for theconcentration range of 10- 100 ng/mL is also shown in Figure 3.
