International sales of Twin-QCM high-precision gas sen

July 12, 2019 (JST)

Nihon Dempa Kogyo Co., Ltd. (NDK) and the Japan Aerospace Exploration 
Agency (JAXA) would like to announce that NDK has strengthened 
international sales of the Twin-QCM sensor, which the two 
organizations jointly developed to perform, under vacuum, high-
precision measurement of outgases emitted from spacecraft components/
(The completion of development of Twin-CQCM was announced in March 
2017 and the sales of Twin-CQCM and Twin-TQCM sensor modules began 
in November 2018.)

Prior to the commencement of international sales, it was ensured 
that Twin-QCM meets the European Union's CE marking*1 requirements. 
By placing CE mark label, it has been proved that Twin-QCM satisfies 
international standards, as well as complies with EU’s directive s 
for products to be exported to the region, making it possible for 
the sensor to be sold on the European market.

Twin-QCM outperforms existing systems in terms of precision and 
stable temperature compensation and is expected to greatly help 
spacecraft developers in their efforts to address the issue of 
contamination*2. The contamination is caused by spacecraft 
outgassing, and JAXA is already utilizing the sensor to gauge 
outgases emitted from materials used for satellites. JAXA will 
expand the usage of the sensor to include the measurement for a 
satellite in its entirety in order to pursue optimum measures 
against the contamination.

In addition to the space industry, NDK is also eyeing other 
industries as its targets and promoting Twin-QCM for use in the 
analysis of adhesives for in-vehicle equipment as well as of heat-
dissipating and other organic materials. The company will exhibit 
the sensor in the Automotive Engineering Exposition 2019 Nagoya*3, 
which will be held at the Port Messe Nagoya between July 17 and 19. 
NDK is planning to fully roll out the sensor as a product developed 
jointly with JAXA which bears the logo of "JAXA COSMODE*4" in 
organic material, semiconductor, construction material, and other 
industry markets where precise gauging of outgases is of primary 
concern to curb contamination.

*1 CE marking 
A manufacturer's self declaration mark that certifies conformity 
with EU standards, which are required to be attached to designated 
products sold in the European region.

*2 Contamination
In the outer space, contamination caused by outgasses from plastics, 
adhesives, and other materials used for manufacturing poses a 
problem. Contamination on the surfaces of telephoto lenses equipped 
in earth and astronomical observation satellites may deteriorate the 
optical performance and image quality and even reduce the lifespan of 
the observation instruments. Therefore, the selection of appropriate 
materials based on accurate measurement is essential to minimize the 
emission of outgases. 

*3 Automotive Engineering Exposition 2019 Nagoya
An automotive engineering exhibition organized by the Society of 
Automotive Engineers of Japan, which will be held at the Port Messe 
Nagoya between July 17 and 19. NDK will exhibit the sensor in Booth 
No. 109.
