Gasi koromatogarafe. mwayi wa njira

Gasi koromatogarafe - kusanthula njira, bwino kwambiri chitukuko ongolankhula. Kuti kuphunzira mosamalitsa maziko ake ongolankhula ndi othandiza anathandiza pa zaka khumi zapitazi, chitukuko mofulumira njira imeneyi.

Amadziwika kuti mpweya koromatogarafe wosiyana njira zina kuti mpweya ntchito m'menemo monga gawo yam'manja. Gawo n'kupuma akhoza kukhala olimba kapena madzi. Malinga izi zikusonyeza kumamatira mpweya kapena gasi madzi koromatogarafe.

Kulekana kwa zosakaniza zinthu mu zipangizo monga chromatograph mpweya, ndi chifukwa kubwerezabwereza kaŵirikaŵiri ndondomeko ya kufalitsa zigawo zikuluzikulu pakati pa madzi n'kupuma kapena gawo kolimba ndi mpweya ikuyenda. The ndondomeko kulekana zachokera kusiyana osakhalitsa ndi solubility wa analytes. chimodzi, amene osakhalitsa pa anapatsidwa kutentha kwambiri ndi zosakwana solubility wa gawo n'kupuma kudzalimbikitsa mwa ndime liwiro.

Ntchito gasi monga chotengera anagubuduza zimathandiza kupeza ubwino monga kulekana kwa zinthu constituent momveka ndi liwiro kusanthula. chitsanzo mayeso anadzetsa ndime mu mawonekedwe gaseous kapena mu mawonekedwe nthunzi. Njira imeneyi n'zotheka kuti tisanthule mpweya komanso madzi ndi zinthu olimba, amene kumasulira mu boma anakhumba ndi magetsi. Pa nkhani imeneyi, mu mpweya koromatogarafe kutentha limene dongosolo lonse, n'chofunikira zofunika kwambiri. malire Magwiridwe kwa mpweya kumamatira kusanthula njira ranges ku 70 600 ° C, ndi gasi madzi - 20 400 ° C. Makampani amapangira mafuta chromatograph, amene amalola mapulogalamu kutentha pasadakhale.

Njira imeneyi zimathandiza kuti tisanthule chinthu maselo kulemera zosakwana 400. Iwo si kuwola ndinso pa evaporation, ndipo sasintha dongosolo awo condensation wotsatira.

Makamaka kumapeto mawunikidwe ntchito koromatogarafe gasi madzi. Poyerekeza ndi mpweya kumamatira lili ndi ubwino, amene makamaka kugwirizana ndi osiyanasiyana zotheka n'kupuma madzi gawo, ndi chiyero mkulu ndi chofunika kwambiri, ndi homogeneity zakumwa.

Gasi koromatogarafe - njira mofulumira, yodziwika ndi lolondola mkulu, tilinazo ndi luso automate. The amagwiritsidwa ntchito mwanjira ndi kusinthasintha njira ntchito kudziwa nkhani zosiyanasiyana chipangizo. Gasi koromatogarafe kuti ntchito kwa kusanthula kachulukidwe amapereka zotsatira lomveka, amene si chipeneko.

Njira angathetse ambiri mawunikidwe mavuto, kugawaniza ndi kudziwa chiŵerengero cha kugwirizana kwa osachepera kuthamanga nthunzi. njira A mpweya koromatogarafe ntchito mankhwala kuyeretsedwa, komanso yogawanika m'zigawo munthu zosakaniza ndi. Ndi kwenikweni kulekana kwa zikuchokera ofanana zinthu zomwe a m'kalasi lomwelo: organic zidulo, alcohols, chimasanduka.
