Background technology
In transformer oil, furfural is a kind of main compound that in transformer, the degraded of solid insulation paper generates.Generally have employed the higher high performance liquid chromatography of operability at present both at home and abroad and detect furfural content in oil, by furfural content in test oil, to assess the paper insulated degree of aging of transformer, but utilize high performance liquid chromatography to detect in oil before furfural content, first furfural will be extracted from transformer oil sample.Solid phase extraction is a kind of extracting process that efficiently can extract furfural in transformer oil rapidly of rising in recent years.When utilizing solid phase extraction to extract furfural in transformer oil, the amount of oil samples is generally no less than 10ml, and needs to use a large amount of reagent, and as in flushing process, the normal hexane reagent of utilization is generally greater than 20mL.Critical component solid-phase extraction column in solid phase extraction generally all only has the capacity of 5 ~ 6mL.Therefore, when a large amount of oil samples of needs or reagent flow through solid-phase extraction column, once 5 ~ 6mL can only be imported.Oil samples needs oil samples all to be flow through solid-phase extraction column through twice operation, and wash reagent then needs to operate for four times.Operation like this not only complicated operation, loses time, and needs operating personnel's energy high concentration, and easily understands misoperation, extraction results mistake.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of device improving vacuum extractor sample introduction efficiency, once can not only complete the operation of oil samples or reagent, and can regulate the flow velocity of oil samples or reagent.
For achieving the above object, the utility model adopts following technical proposals:
A kind of device improving vacuum extractor sample introduction efficiency, comprise support, upper strata installing plate, lower floor's installing plate, glass syringe, restrictor, stream guiding tube, upper strata installing plate is shaped with syringe spacing hole, lower floor's installing plate is shaped with syringe spacing hole, glass syringe is by the spacing hole of upper strata installing plate, end opening place is stuck in the spacing hole place of lower floor's installing plate, after stream guiding tube overcoat restrictor, connects glass syringe end opening.
Glass syringe is without the need to syringe needle and piston.
Aqueduct is squeezable soft plastic pipe, and interior diameter need match with glass syringe end opening.
Restrictor and aqueduct match, and effectively can regulate the flow of aqueduct.
Coaxial injectors spacing hole on two-layer parallel installing plate is two rows.
Described upper strata installing plate spacing hole, the little overall diameter that should be greater than glass syringe in aperture, makes the free taking and placing of glass syringe energy.
Described lower floor's installing plate spacing hole, aperture should be less than the overall diameter of glass syringe, but should be greater than the diameter of glass syringe end opening, and glass syringe should free taking and placing.
After the distance of two-layer parallel installing plate is installed with syringe, syringe is reinforced as easily by stable.
The beneficial effects of the utility model are,
1, device simple and efficient of the present utility model, comprise a support, at the upper surface of support, two-layer parallel installing plate is installed, glass syringe is arranged on two-layer installing plate, after restrictor installed by aqueduct, be connected with glass syringe end opening, under natural gravity effect, the oil sample in glass syringe or reagent can flow down naturally, and the capacity of glass syringe is 20mL, disposablely can hold Solid-Phase Extraction oil sample used or reagent, ensure that the disposable operation of oil sample or reagent completes;
The mozzle of 2, the utility model reagent bottle cleaning device is provided with restrictor, effectively can regulates the flow of Solid-Phase Extraction oil sample used or reagent, to control the amount flowing into solid-phase extraction column.
