    摘要: The invention relates to a leak detector comprising a first sensor for detecting a gas component (helium) in a gas taken in. Because the sensor is susceptible to saturation or contamination, a second sensor is provided. The sensor is a thermal conductivity sensor. The thermal conductivity sensor has a lower detection sensitivity, yet, at a high concentration of the gas component, it does not risk being contaminated. The two sensors together allow for a large detection range, from extremely sensitive measurements to instances with high concentrations of the gas components as those which can occur with gross leaks.

    摘要: A method for detecting an enthalpy change includes providing a first mixture and a second mixture to a drop generator. The first mixture includes a ligand. The second mixture contains a target molecule. The method further includes generating a drop in the drop generator. The drop includes the target molecule, a temperature-sensitive reporter compound, and the ligand. The method also includes measuring a property of the temperature-sensitive reporter compound in the drop to determine an amount of enthalpy change that has occurred.
