High performance liquid chromatography determination method of tetracycline antibiotic in soil

InactiveCN102401818AEasy to separateReduced vacuum drying stepsComponent separationElutionSolid phase extraction
The invention relates to an environmental analysis detection method, and specifically, relates to a high performance liquid chromatography determination method of tetracycline antibiotic in soil. The high performance liquid chromatography determination method of tetracycline antibiotic in soil comprises the following steps of 1, a sample collecting and preparation process comprising collecting soil in a plough layer having thickness of 0 to 20 centimeters, wherein soil in a composting place and field edges is not adopted, uniformly mixing multiple single-point samples, carrying out quarteringreduction to obtain a mixed soil sample having weight of about 1kg, putting the mixed soil sample into a sealing bag, bringing the sealing bag with the mixed soil sample back with low-temperature preservation in the dark, putting the mixed soil sample into a room, drying in air, crushing, screening by a nylon sieve of 60 meshes, and weighing 2g of the mixed soil sample for next use, 2, an extractpreparation process, 3, an extraction, purification and enrichment process, and 4, an elution, volume metering and detection process. The high performance liquid chromatography determination method of tetracycline antibiotic in soil has normalized processes, reduces a vacuum drying process, produces low jamming, shortens operation time and improves operation accuracy. Through connection between astrong anion solid phase extraction column and a C18 inverted solid phase extraction column in series, purification and enrichment effects are greatly improved.

Operation method for replacing 10kV drop-out fuse in on-load manner

ActiveCN102931609ADoes not affect electricity consumptionAvoid investment and re-investment timeApparatus for overhead lines/cablesElectricityFailure rate
The invention relates to the field of a drop-out fuse in a distribution line of a power grid, and particularly relates to an operation method for replacing a 10kV drop-out fuse in an on-load manner. The operation method is characterized in that an insulation drainage wire bypass drop-out fuse is directly connected with the two ends of the drop-out fuse to be replaced for splitting current, and thus the 10kV drop-out fuse is replaced in the on-load manner and under the condition of continuously charging a load. Compared with the prior art, the operation method has the beneficial effects that the load on the lower end of equipment can be charged continuously in the operation period, and when the on-load operation is implemented by an electrified operation method, the delivery time and the redelivery time of the equipment can be avoided, the operation flow is shortened, and the electricity utilization of a user can not be affected in the operation period; the failure rate of 10kV primary equipment can be reduced greatly, and the power supply quality can be improved effectively; and the drop-out fuse is replaced in the on-load manner and with an insulation drainage wire, the operation is conducted by a double-man double-insulation bucket truck, the operation time is short, few tools are used, resources can be saved effectively, and the power supply reliability is improved.

Operation method for on-load replacing of 10kV pole-mounted disconnector

InactiveCN103001142ADoes not affect electricity consumptionAvoid investment and re-investment timeApparatus for overhead lines/cablesTruckLine current
The invention relates to the field of 10kV pole-mounted disconnectors, in particular to an operation method for on-load replacing of a 10kV pole-mounted disconnector. The operation method is characterized in that insulating current guiding lines are electrifiedly and directly connected, by an insulating glove operation method, to two ends of the pole-mounted disconnector for current shunting, and operations are performed through a double-man double-insulating-bucket-arm truck. Compared with the prior art, the operation method has the advantages that 1) by using the insulating current guiding line current shunting method for on-load replacing of the 10kV pole-mounted disconnector, power supply for lower-end load of equipment can be continued during operation, equipment launching and relanunching can be avoided during on-load operations utilizing an electrified method, operation process is shortened, power supply reliability is improved effectively, and power utilization of users is not influenced during the operation; 2) fault rate of 10kV primary equipment can be reduced greatly, and power supply quality is improved effectively; and 3) by the operation utilizing the double-man double-insulating-bucket-arm truck, operation time is short, few tools are used, energy is saved effectively, and power supply quality is improved.
