In July 2019, an amendment to the RoHS directive will add 4 phthalates to the list of restricted substances. These 4 chemicals are widely used for insulated coating materials, electrical insulation tapes and packing films.
The HM1000 is a dedicated instrument designed for fast, easy, on-site screening of phthalates. In addition to easy operation, the HM1000 features high-throughput testing that achieves automated analysis of 50 samples in approximately 8 hours.
Vaporized compounds are ionized and directly analyzed by a mass spectrometer enabling high-speed measurement.(Separation column is not required)
The accurate and smooth performance of the autosampler (standard equipment) allows continuous automatic analysis of up to 50 samples. During the analysis, operators are free to engage in other tasks, resulting in a streamlined operation and reducing workloads.
Place the sample in the sample pan and position it on the sample tray. Next, by following simple software steps, measurements will be started by the autosampler. The autosampler diagram is displayed on the software and the progress of measurements and the results (PASS/FAIL judgment) can be verified easily.
Nitrogen gas is used as the carrier gas. Using nitrogen gas generator (option available in Japan or locally sourced), a power source is the only utility required for operation. Helium gas and liquid nitrogen are not needed, which helps keep operating costs low.

The m/z value obtained from analyzing the sample can be used to estimate the component that is contained in the sample.
A peak will appear at molecular weight +1 for each phthalate after protonation.
The concentration of the Phthalates contained in the sample can be estimated using the ion intensity profile and can be compared to the regulations acceptable limit.
