Blunt-tipped Needle Clogged, How To Do?
Dr.c | Updated: Aug 14, 2017

Blunt-tipped Needle clogged, how to do?
You can use the organic solvent to clean the inner wall of the Blunt-tipped Needle.When cleaning, please pay attention to check whether the injection Blunt-tipped Needle putter can move smoothly, if the injection Blunt-tipped Needle putter is not smooth movement, then It is recommended to wipe it out with a soft cloth dampened with an organic solvent.
    Repeated use of organic solvent aspirations. If the resistance of the blunt plunger putter is increased after several aspirations, there are still some small contaminants present. After this happens, the cleaning process is repeated The
    If the injection of Blunt-tipped Needle putter can be smooth and smooth movement, check the Blunt-tipped Needle is blocked. Repeatedly rinse the Blunt-tipped Needle with an organic solvent and check the shape of the sample being pushed out of the Blunt-tipped Needle.
    If the Blunt-tipped Needle is normal, the sample will flow out in a straight line. If the Blunt-tipped Needle is clogged, the sample will be ejected in a fine or mist from one direction, or even if the solvent flows out in a straight line Check out the situation is better than the normal situation (and a new non-clogged injection Blunt-tipped Needle compared to the situation can be out).
The clogging of the Blunt-tipped Needle will destroy the reproducibility of the analysis; for this reason the maintenance of the Blunt-tipped Needle is necessary. Remove the plug in the Blunt-tipped Needle with something like a wire, and use a Blunt-tipped Needle only if the sample is flowing out normally. The use of a liquid suction device or a Blunt-tipped Needle cleaner can also effectively remove contaminants from the Blunt-tipped Needle tube.
    Blunt-tipped Needle is mainly used in gas chromatography, liquid chromatography equipment injection process, these large-scale chromatography analysis equipment has been widely used in all aspects of modern society. From the days of the space shuttle, to the water travel aircraft carriers, are using gas chromatography to monitor the quality of the gas in the cabin; from daily life in the food and cosmetics, to a variety of chemical production process control and product quality inspection, from the judicial test In the identification of the material to the geological exploration of oil and gas fields to find, from the disease diagnosis, medical analysis, to the archaeological excavation, environmental protection, gas chromatography, liquid chromatography technology is widely used. For each chromatographic analyzer, Blunt-tipped Needles are indispensable for the injection device, each chromatogram must be configured with different models of the number of Blunt-tipped Needles.
