Abstract
A method is shown for the analysis of hydrocarbon based fuels comprising the following steps: a) the use of a tunable diode laser (TDL) whereby several wavelengths of light can be emitted, b). transmission of said light through a transparent flow cell or flow chamber containing the fuel, c). measurement of the transmitted light with an optical detector positioned on the opposite site of the cell/chamber, d). detection of signals and storage on a computer memory, e). computer-based analysis of measurements, f). use of an algorithm and a chemical reference library for subsequent quantitative analysis of the hydrocarbon compounds.
Claims17
Method for analyzing a fuel, preferably hydrocarbons, characterized in that the method includes the following steps:
- a) Tuning of a laser to send out different wavelengths of light,
- b) Illumination with the laser light of a chamber or container/flow line holding fuel,
- c) Measuring of transmitted laser light after it has passed the chamber/container/flow line with an optical detector,
- d) Collecting and storing of measurements,
- e) Analyzing the measurements by means of a microcontroller,
- f) Calculate the concentrations by means of an algorithm arranged in the microcontroller and a chemical reference library.
