(China) GC-7890 Ditert-butyl Peroxide Residue Detector
Nsalu yosungunula imakhala ndi mawonekedwe ang'onoang'ono pore, porosity kwambiri komanso kusefedwa kwakukulu, ndipo ndiye chinthu chofunikira kwambiri popanga chigoba. Chida ichi chimatanthawuza GB/T 30923-2014 pulasitiki Polypropylene (PP) Melt-blown Special Material, yoyenera polypropylene monga zopangira zazikulu, ndi di-tert-butyl peroxide (DTBP) monga kuchepetsa wothandizila, kusinthidwa polypropylene kusungunula-wowomberedwa zinthu zapadera.
Chitsanzocho chimasungunuka kapena kutupa mu zosungunulira za toluene zomwe zili ndi n-hexane yodziwika ngati muyezo wamkati. Mulingo woyenera wa yankho udamwedwa ndi microsampler ndikulowetsa mwachindunji mu chromatograph yamafuta. Pazifukwa zina, kusanthula kwa gasi chromatographic kunachitika. Zotsalira za DTBP zidatsimikiziridwa ndi njira yamkati.
1) Chromatograph ya mpweya, cholowera cha capillary, chowunikira cha FID,
2) Unikani malire
3) Mzere wa kapilari: AT.624 30m*0.32mm*1.8μm,
4) Chromatographic workstation software,
5) N-hexane, chromatographic koyera;
6) Di-tert-butyl peroxide, kusanthula koyera;
7) Toluene, kusanthula koyera.
GC-7890 Gas chromatograph imagwiritsa ntchito makina owongolera makompyuta ndi mawonedwe akulu aku China, mawonekedwe ake ndi okongola komanso osalala. Makiyi a kiyibodi omwe angopangidwa kumene ndi osavuta komanso othamanga, ndipo mabwalo ndi zigawo zomwe zimatumizidwa kunja, kotero kuti chidacho chimagwira ntchito mokhazikika komanso chodalirika.
Ⅰ. Kuphatikizana kwakukulu kwa dera, kulondola kwambiri, ntchito zambiri
1. Ogwiritsa ntchito makiyi a microcomputer onse, 5.7 inch (320 * 240) chiwonetsero chachikulu cha LCD m'Chitchaina ndi Chingerezi, Chitchaina ndi Chingelezi chowonetserako chingasinthidwe momasuka, kuti akwaniritse zofunikira za magulu osiyanasiyana a anthu, kukambirana kwa makina a munthu, kosavuta kugwira ntchito.
2.Microcomputer control hydrogen flame chowunikira kuti mukwaniritse ntchito yoyaka yokha, yanzeru kwambiri. Watsopano Integrated digito zamagetsi dera, mkulu kulamulira mwatsatanetsatane, khola ndi odalirika ntchito, mpaka 0.01 ℃ kutentha kulondola molondola.
3.Gas chitetezo ntchito, kuteteza ndime ndi matenthedwe conductivity dziwe, electron Capture detector.
Zili ndi ntchito yodzizindikiritsa poyambira, zomwe zimathandiza ogwiritsa ntchito kudziwa mwamsanga chifukwa ndi malo a kulephera kwa chida, ntchito ya stopwatch (yosavuta kuyeza kuthamanga), kulephera kwa mphamvu yosungirako ndi ntchito yotetezera, ntchito yotsutsana ndi kusintha kwa kusintha kwa mphamvu, kuyankhulana kwa data pa intaneti ndi ntchito yakutali. Ntchito yoteteza kutentha kwambiri ndiyotsimikizika
Chidacho sichinawonongeke ndipo chili ndi dongosolo la kukumbukira deta lomwe silifuna kukonzanso kulikonse.
Ⅱ.jekeseni dongosolo lapadera kapangidwe, akhoza kukhala otsika kudziwika malire
1. Mapangidwe apadera a doko la jakisoni kuti athetse tsankho; Ntchito yolipiridwa ndi magawo awiri sikungothetsa kusuntha kwa mzere woyambira chifukwa cha kutentha komwe kumakonzedwa, komanso kumachepetsa mphamvu ya phokoso lakumbuyo kuti mupeze malire ozindikira.
2.Ndi gawo lodzaza, dongosolo la jakisoni la capillary shunt/non-shunt (lokhala ndi ntchito yoyeretsa diaphragm)
3.Optional basi / manual gasi njira zisanu ndi imodzi jekeseni, headspace jekeseni, matenthedwe kusamvana jekeseni, methane Converter, basi jekeseni.
Ⅲ、Kutentha kokonzedwa, kuwongolera kutentha kwa ng'anjo, kukhazikika kwachangu
1.Eight-kuti liniya kutentha anakonza, pambuyo khomo ntchito photoelectric lophimba contactless kamangidwe, odalirika ndi cholimba, wanzeru pambuyo pa khomo dongosolo stepless variable mpweya voliyumu, kufupikitsa pulogalamu pambuyo kuwuka / dontho la chojambulira dongosolo khola bwino bwino nthawi, kwenikweni kuzindikira pafupi chipinda kutentha ntchito, kutentha ulamuliro molondola ± 0.01 ℃, kukwaniritsa zofunika zosiyanasiyana kusanthula.
2.Large buku la ndime bokosi, wanzeru kumbuyo khomo dongosolo stepless variable mpweya voliyumu mkati ndi kunja, kufupikitsa pulogalamu pambuyo kukweza / kuziziritsa chowunikira dongosolo khola bwino bwino nthawi; Kutentha ng'anjo dongosolo: yozungulira kutentha +5 ℃ ~ 420 ℃.
3.The kutchinjiriza zotsatira ndi bwino: mzati bokosi, vaporization, kuzindikira ndi madigiri 300, bokosi kunja ndi chivundikiro pamwamba ndi zosakwana madigiri 40, kusintha mlingo experimental, kuonetsetsa chitetezo cha wosuta.
4.Mapangidwe apadera a chipinda cha vaporization, voliyumu yaying'ono yakufa; Chalk m'malo: jekeseni jekeseni, liner, polarizer, wosonkhanitsa, nozzle akhoza m'malo ndi dzanja limodzi; Kusintha kwakukulu kwa thupi: mzere wodzaza, capillary sampler ndi chowunikira zitha kuchotsedwa kwathunthu ndi wrench, kukonza kosavuta.
Kumverera kwakukulu, chowunikira chokhazikika kwambiri, kukwaniritsa zosowa za ziwembu zosiyanasiyana
Hydrogen flame ionization detector (FID), thermal conductivity cell detector (TCD), electron Capture detector (ECD),
Flame Photometric detector (FPD), Nitrogen ndi Phosphorus detector (NPD)
Mitundu yonse ya zowunikira zimatha kuyendetsedwa paokha kutentha, chojambulira chamoto wa hydrogen ndi chosavuta kugawa ndikuyika, chosavuta kuyeretsa kapena m'malo mwa nozzle.
Khomo la jekeseni
