New technical solutions

Chromalytica AB develops sensor technologies that will take chemical analyse into a new era. Application areas range from general chemical analyse to revolutionary medical diagnoses based analyse of chemical substances in exhaled air.

Technology
The basic GC-UV technology was invented by Dr. Kaye in US as early as in the 1960-ies and then developed from the early 1980-ies and onwards by Dr Verner Lagesson and licentiate Ludmilla Lagesson-Andrasko at the department of Department of Occupational Medicine, Linköpings University, Sweden and has now with the latest development taken the step into being a unique state of art supplement to existing solutions, allowing analysis never before achieved.

Air with a mixture of numerous volatile chemical  substances in gas phase is trapped and fed into a gas chromatograph where the various chemical substances are separated by time through a pipe.
After separation, the chemical substances are in a sequence fed through a detector where very short wave length light is absorbed by the substances in such a way that the absorbance is made by a spectrometer in a spectral way, with a spectrum unique to each individual substance. The function is quantum mechanical with a 100% identification. Matching of the spectra is then made to the unique Chromalytica spectra database for final identification.

Applications
The newly developed technique has a unique ability to identify and quantify extremely low concentrations of VOC (Volatile Organic Compounds) in exhaled air thereby adding a new technique for diagnoses but also for monitoring of treatment. In the future VOC analysis is likely going to be the analytical procedure of choice for in many medical conditions but may already now be used as a supplement to blood and urine analysis.

Accuracy
Chromalytica design and manufacturing comprises decades of experience in extremely high precision and accuracy with in vital mechanical parts single micrometer tolerances.The instrument is designed to the highest standards for detection with ability to detect, identify and quantify substances in gas phase down to well below the pico gram level.

Validation
The Instrument is under validation under very strict conditions in order to have the instrument at its maximum of accuracy and specificity.

Sensitivity
The method has the ability to detect and identify very small quantities and very low concentrations of a large number of chemical substances either as individuals or in complex mixtures.

Chemical spectra data base
Chromalytica owns a unique sub 250 nm wave lengths absorption spectra database for accurate matching.
