OralChroma uses Gas Chromatography Technology

Product Announcement from FIS Inc.

OralChroma uses Gas Chromatography Technology-Image

We will exhibit and demonstrate OralChroma at "IDS (International Dental Show)" (March 12 to 16, 2013) in Cologne, GERMANY. New OralChroma will be displayed as a reference product. Our booth No. is C-071 in Hall 2.2.

Three major halitosis components are hydrogen sulfide, methyl mercaptan, and dimethyl sulfide. The OralChroma measures Volatile Sulfide Components (VSC) in the breath and separates them into the above three components. About 1000 sets of OralChroma have been supplied to dentists, universities, and laboratories in the world since 2002.

Separating halitosis into three major components with high precision

Since the OralChroma uses gas chromatography technology, causes of halitosis can be precisely analyzed to confirm breath odor diagnostics treatment.

Simple breath sampling with a supplied syringe

You can freely select where to place the OralChroma without being worried about permanent installation.

Sophisticated data management software attached (DataManager)

DataManager is a graphical software providing halitosis strength level, patient's data history, etc.

* OralChroma is a measuring device.
