Objective To develop a portbable incubator for on-site cultivation of microorganisms in foods and drinking water.Methods Cultivation temperature was set as required by the temperature for various microorganisms and PID was controlled via the single chip microcomputer and configuration screen .Then, the framework of the incubator was designed and assembled.Finally, the cultivation effect was tested .Results The incubator was compact and portable .The deviation of the temperature was in the range of 1℃.The hold time of self-contained power could exceed 8 h.In addition, the cultivation effect of our fabricated incubator was not significantly different from that of the commercial electro-heating standing-temperature cultivator used in laboratories .Conclusion The incubator is suitable for on-site detection of microorganisms in foods and drinking water , which is significant for spotting and removing the hidden dangers from microorganism contaminations in foods and drinking water in order to protect the health of soldiers .

Objective: To establish a method for determining cyclohexanol in urine by headspace solid-phase microextraction (HS/SPME) coupled with gas chromatography (GC) . Methods: After the urine sample was hydrolyzed by β-glucuronidase, 2.0 g of NaCl was added, then the analyte in urine was adsorbed by a CAR/PDMS solid phase micro-extraction head in a water bath at 50 ℃ for 20 min. And the extraction head was inserted into the gas chromatograph gasification chamber to desorb, the analyte was detected after separated by the capillary through the flame ionization detector. Results: The linear range of the method was 0.1-5.0 mg/L with the correlation coefficients (r) 0.999. The average recovery was 84.5%-96.3%, the inter-day precision was 3.81%-6.00%, and the detection limit was 0.03 mg/L. Conclusion The method is founded to be low detection limit, simple operation and no need of organic solvent. So it is suitable for the detection of cyclohexanol in urine of occupational exposure to cyclohexanone.
