Welcome LAR


BOSTON, MA – January 18, 2018. Union Park Capital, a Boston based private equity firm with focus on lower middle-market industrial technology investments, today announced the acquisition of LAR Process Analysers AG (“LAR”), located in Berlin, Germany. LAR develops and manufactures water analyzers for industrial, environmental and municipal applications based on highly differentiated high-temperature combustion technology. LAR will join Cosa Xentaur Corporation and Alpha Omega Instruments as an independent operating entity under Union Park’s newly created Process Insights Holdings platform.

“We are very excited about this acquisition,” notes Morgan Jones, Managing Partner of Union Park Capital. “LAR is a perfect example of everything we look for – the business has product differentiation, a strong brand name and a highly technical workforce with deep application knowledge. Today LAR has an incredibly strong presence in Europe, but as part of Process Insights, LAR will be able to expand internationally taking advantage of a global sales network.”

“The Union Park Capital team has extensive experience investing in family owned European businesses, specifically in Germany,” said Dr. Werner Arts, Founder and Chairman of LAR. “They have a proven track record not only of success, but also of trust and integrity. I believe LAR has found an ideal home at Union Park and Process Insights.”

The strategic announcement comes just weeks after Union Park announced the acquisition of Cosa Alpha Omega Instruments late in 2017. LAR, together with the other business units within Process Insights, will continue to develop and invest in cutting-edge technologies in process analysis. As usual with Union Park’s historical business practice, LAR will remain in Berlin, Germany.

Product Bruchure

Continuous TOC determination.
Using the UV persulfate method.

QuickTOCuv is an online measuring system that determines the parameter TOC using the UV persulfate method. In addition, different versions of the measuring device can be supplied and it can thus also be used in Ex zones. TOC determination is carried out in accordance with the standards DIN EN 1484:1997 and US-EPA 415.2.

The measuring technology. Reliable.

The QuickTOCuv process controls have been optimised in all areas. Additional sensors and carrier gas preparation are optional. Reliable operation is guaranteed by the separation of the analytical compartment from the electronics and by the use of high-quality materials.

System checks. Automatic.

QuickTOCuv automatically carries out regular checks to assess correct function of NDIR detector by zero point correction and sensitivity tests. This ensures that any deviations are rapidly detected and guarantees precise results.
