Embodiment 1
[0068] Such as figure 1 As shown, the device for measuring 8-hydroxyisomeric prostaglandin F2α in urine of this embodiment includes a six-way valve 7 with a sample inlet, a sampler 6, an enrichment pump 5, and an analysis pump 2 , a detector 4, an online solid phase extraction column 1, an analysis column 3 and a chromatographic workstation. The six-way valve 7 with the sample inlet is provided with seven ports, namely the first port to the seventh port.
[0069] The detector 4 is connected to one end of the analytical column 3, the other end of the analytical column 3 is connected to the third port, the analytical pump 2 is connected to the second port, the enrichment pump 5 is connected to the sampler 6, and the sampler 6 is connected to the seventh port .
[0070] The six-way valve 7 with a sample inlet is used for switching between the solid phase extraction column 1 and the analysis column 3; the solid phase extraction material of the solid phase extraction is graphene ...
Embodiment 2
[0079] The device of this embodiment is the same as that of Embodiment 1.
[0080] The present embodiment is based on the assay method of 8-isomer prostaglandin F2α in the urine of above-mentioned device, carries out as follows:
[0081] The test samples were urine samples from light smokers. Take 7.5 mL of smoker urine sample collected, add 200 µL of internal standard working solution, and dilute to 10 mL with methanol; shake well, bring back to the laboratory within 20 h, and centrifuge at 20,000 r / min for 10 min at high speed; Take about 5.0 mL of the supernatant, filter it with a 0.25 µm syringe filter, and use it for online solid-phase extraction enrichment.
[0082] The sample injection volume was 2.0 mL, and after the sample injection, the enrichment pump used 25% methanol as the mobile phase at a flow rate of 1.0 mL / min to transport through the solid phase extraction column for enrichment. After the sample completely passes through the solid-phase extraction column, ...
Embodiment 3
[0085] The device of this embodiment is the same as that of Embodiment 1.
[0086] The present embodiment is based on the assay method of 8-isomer prostaglandin F2α in the urine of above-mentioned device, carries out as follows:
[0087] The samples tested were urine samples from moderate smokers. Take 7.5 mL of smoker urine sample collected, add 200 µL of internal standard working solution, and dilute to 10 mL with methanol; shake well, bring back to the laboratory within 20 h, and centrifuge at 20,000 r / min for 10 min at high speed; Take about 5.0 mL of the supernatant, filter it with a 0.25 µm syringe filter, and use it for online solid-phase extraction enrichment.
[0088] The sample injection volume was 1.5 mL, and after the sample injection, the enrichment pump used 25% methanol as the mobile phase at a flow rate of 1.0 mL / min to transport through the solid phase extraction column for enrichment. After the sample has completely passed through the solid-phase extraction...
