A device for igniting a sample arranged in a container for a flashpoint determination test and/or a combustion point determination test. The device has an electric igniter, which has an ignition tip having a partially or completely encapsulated electric wire; and a traversing device, which is configured for traversing the ignition tip of the electric igniter to a defined position within the container.

A gas measuring apparatus for a secondary battery comprises: a chamber accommodating a secondary battery therein; a heater unit applying heat to the chamber to ignite the secondary battery accommodated in the chamber; a collection tube connected to the inside of the chamber to collect a gas generated in the secondary battery; a vacuum unit connected to the collection tube to vacuumize the inside of the chamber so as to introduce the gas into the collection tube; and a gas measuring unit measuring an amount of gas introduced into the collection tube.

The method for analyzing an ozone concentration comprising the steps of: providing at least one catalytic chamber having an ozone decomposition path between an inlet portion and an outlet portion thereof; receiving a sample flow of gas containing ozone by the inlet portion of the at least one catalytic chamber and along the ozone decomposition path; decomposing a totality of the ozone of the sample flow of gas into oxygen in an exothermic reaction along the ozone decomposition path of the catalytic chamber; measuring a first temperature value at a first position and measuring a second temperature value at a second position, the first and second positions being associated with the inlet and outlet portions; evaluating the ozone concentration of the sample flow of gas based on the temperature difference between the second temperature value and the first temperature value and calibration data; and generating a signal indicating the evaluated ozone concentration.

A portable, compact, real-time and accurate sensor and method for deriving a physicochemical property of a liquid fuel, such as cetane number, carbon content, carbon/hydrogen (C/H) atomic ratio, or heating value (net heat of combustion). The sensor comprises a constant-volume ignition chamber equipped for measuring ignition delay and magnitude of a peak rise in pressure or temperature following dispensation of a liquid fuel into the chamber. The sensor utilizes air at atmospheric pressure and microliter quantities of fuel. The sensor can be implemented in real-time refinery operations for blending diesel fuels that meet government mandated cetane number standards as well as in applications for standardizing jet, biodiesel, and synthetic fuels, which presently are not classified by any physicochemical property.
