Abstract
A determination device for hydrocarbon emissions of a thermal engine including an inspection probe for removing a sample volume from a liquid, a measurement channel for conducting the sample volume via an ion source apparatus to a broadband measurement apparatus that is configured to determine a spectrum to be measured in one step, wherein the ion source apparatus is configured for soft ionization and the measurement apparatus forms an intensity signal sequence across the mass spectrum and is configured as a simultaneously measuring “time-of-flight” detector or as a “double-focusing sector field mass spectrometer in Mattauch-Herzog geometry.”
Claims18
A determination device for hydrocarbon emissions of a thermal engine, the determination device comprising:
- a sampling probe for taking a sample quantity from a fluid,
- a measuring channel configured for conducting the sample quantity via an ion source unit to a broadband measuring unit such that hydrocarbons from unburned portions of a fuel of the thermal engine and hydrocarbons from a lubricant oil of the thermal engine are conducted to the broadband measuring unit,
- wherein the ion source unit is configured for soft ionization, and
- wherein the broadband measuring unit is configured to determine a spectrum of both the hydrocarbons from unburned portions of the fuel of the thermal engine and the hydrocarbons from the lubricant oil of the thermal engine simultaneously in one step in less than 1 ms, and to form an intensity signal sequence over the spectrum, the broadband measuring unit being configured as a simultaneously measuring time-of-flight detector or as a double-focusing sector field mass spectrometer in Mattauch-Herzog geometry.
