Hitachi High-Technologies Launches HM1000 screening equipment for phthalates

-Quick, simple testing for phthalates newly restricted under RoHS directive-


Tokyo, Japan, July 13, 2017 &ndash Hitachi High-Technologies Corporation (TSE: 8036, Hitachi High-Tech) announced today that its wholly owned subsidiary and analytical instrument manufacturer and marketer Hitachi High-Tech Science Corporation (&ldquoHHT Science&rdquo) has developed the HM1000 thermal desorption chemical ionization mass spectrometer to speed up
and simplify testing for four types of phthalates*1 for restriction of hazardous substance (RoHS) regulations. The use of these chemicals will be restricted in the European Union (EU) from July 2019 under the RoHS directive. The HM1000 goes on sale in Japan and overseas on July 13.

The HM1000 comprises three sections: a sample heating unit to gasify the phthalates within a sample an ionizing unit to ionize the gasified phthalates and a mass spectrometer to measure the ionized components produced. Simplification of conventional testing methods enables each sample to be screened for phthalates in under 10 minutes. The preparation procedure is as simple as putting the sample in the sample pan. Specialist software then automatically completes the analysis of sample components, detecting the amount and content percentage of each phthalate present. In addition, an auto-sampler allows for continuous automated analysis of up to 50 samples (including any reference specimens), resulting in a streamlined testing process. 

Developed for the screening of phthalates, the HM1000 helps customers not only achieve amended RoHS compliance quickly, but also contributes  to developing productwith lower environmental impact. 

【Main Features
1. High-speed measurement

Simultaneous measurement of multiple components in the gases created from the sample and a newly designed sample heating unit for rapid heating and cooling of samples enable high-speed measurement at a rate of less than 10 minutes per sample.

 2. Simplified measurement

The screening equipment can be easily used for phthalate screening by untrained personnel working in procurement or on the factory floor thanks to an auto-sampler (continuous testing of up to 50 samples) and specially designed software (for automatic detection and characterization of sample components).


3. Low running costs

The equipment only requires electric power and a supply of nitrogen gas, helping to keep operating costs low.
