Description
Technical field
The utility model relates to a kind of total nitrogen and clears up colorimetric complete equipment, belongs to environmental protective chemical industry technical field.
Background technology
At present, traditional total nitrogen digestion tube is glass material, and most pipe lid is that impermeability is not good, therefore in digestion process for the water body easily producing ammonia, the net result of test can be on the low side, even has very large situation, cause ammonia nitrogen value more much higher than total values of nitrogen might.Therefore, need to be improved.
Utility model content
The purpose of this utility model is to provide a kind of total nitrogen to clear up colorimetric complete equipment, to test total values of nitrogen might of sample better.
To achieve these goals, the technical solution of the utility model is as follows.
Colorimetric complete equipment cleared up by a kind of total nitrogen, by clearing up frame and these two parts of colorimetric shelf form, wherein, clear up frame to carry out pre-treatment for sample in pressure cooker inside and clear up, by the first added lid, gluing epiphragma, the first packing ring, clear up frame, clear up socket, lower glue epiphragma and undercarriage lid form, wherein, first added lid is arranged on undercarriage lid top position, the undercarriage portion of covering is placed with lower glue epiphragma, lower glue epiphragma is provided with and clears up frame, clears up in frame to be placed with and multiplely clears up socket; Clear up frame upper and lower and be provided with the first packing ring; First added lid bottom is provided with gluing epiphragma, and gluing epiphragma is placed on clears up socket upper position.Colorimetric shelf is used for the colour developing after Specimen eliminating and colorimetric, be made up of the second added lid, upper glued membrane, the second packing ring, colorimetric shelf and color comparison tube, wherein, second added lid is arranged on colorimetric shelf top position, color comparison tube is provided with in colorimetric shelf, color comparison tube top is provided with glued membrane, is provided with the second packing ring between upper glued membrane and color comparison tube; Second added lid is placed on glued membrane upper position.
In this device, first digestion tube wound packages is cleared up on frame fortunately, put rubber gasket below, cover lower glue epiphragma and undercarriage lid, sample and digestion solution is injected in digestion tube, with water constant volume to scale mark, put gluing epiphragma and the first added lid in the first grommet cover, put into pressure cooker and carry out High Temperature High Pressure and clear up.Clear up after cooling complete, remove the first added lid, gluing epiphragma and the first packing ring, being inverted in by the colorimetric shelf installing color comparison tube clears up on frame, allow color comparison tube with clear up the mouth of pipe tight-lipped close dock after by two shelfs to change place, clear up and be placed on colorimetric shelf, the undercarriage lid of frame will be cleared up, lower glue epiphragma and lower gasket are opened, socket is cleared up with pure water cleaning, residual sample liquids is allowed fully to transfer in color comparison tube, frame is cleared up in removing, nitrite ion is injected in color comparison tube, cover the second packing ring of color comparison tube, upper glued membrane and the second added lid, be inverted back and forth, nitrite ion in color comparison tube is fully contacted with sample, finally carry out colorimetric.
The beneficial effect of this utility model is: this device thoroughly can solve determination of total nitrogen content and be worth problem on the low side, improves sample recovery rate, and makes the mensuration of total nitrogen more specialized.
