A cartridge device (10) for collecting and analysing a breath condensate is disclosed. The device (10) comprises a condensation zone (12) to condense exhaled breath from a subject and cooling means operably connected to the condensation zone (12). The device includes further discrete regions (13) for detection of analyte and measurement of analyte. The condensation zone (12) has a fluid exit connecting the condensation zone (12) to the discrete regions (13).

The invention belongs to the field of detection on physical and chemical characteristics of petroleum products, and particularly relates to a reduced-pressure micro-distillation system for biomass-based blended fuel. The reduced-pressure micro-distillation system comprises a distillation device, a vacuumizing device, a cooling device and a recycling device. The distillation device is individually isolated by a partition plate and comprises a distillation flask, the bottom of the distillation flask is matched with a clamp table, a heater is arranged on the top of the clamp table and clings to the bottom of the distillation flask, the distillation flask is communicated with a sample bottle via a feed pipe with a pump, and the top of the distillation flaks is communicated with a distillation head. The reduced-pressure micro-distillation system has the advantages that the reduced-pressure micro-distillation system is simple in structure and high in external interference resistance, distillation range data of the biomass-based blended fuel can be quickly and accurately measured by the reduced-pressure micro-distillation system, and vapor pressure data of the fuel can be obtained by the reduced-pressure micro-distillation system.

The invention discloses a method for thermal analysis and evaluation of a multi-feature point double-sample cup for inoculation of molten iron in vermicular graphite cast iron, which includes collecting double-sample cups in front of the furnace for thermal analysis and cooling curves of inoculated molten iron in the production of vermicular graphite cast iron, and extracting the inoculated Multiple groups of feature points on the cooling curve of molten iron thermal analysis; bring the extracted multiple groups of feature points into the pre-calibrated inoculum index calculation model for calculation, and obtain the inoculum index calculation value; combine the obtained inoculation index calculation value with the pre-calibrated The inoculation effect index section range is compared, and the inoculation effect of vermicular graphite cast iron is evaluated according to the inoculation effect index section range of the inoculation index calculation value. The invention can make the evaluation of the inoculation effect of the vermicular graphite cast iron molten iron more reasonable and accurate, provide adjustment basis for the dynamic adjustment of the inoculation state in the production process, achieve a good evaluation effect, and ensure the quality of the cast iron molten iron. It also has a certain evaluation effect on the inoculation effect of cast iron molten iron in other graphite forms.
