I-DRK-GC-7890 i-Ditert-butyl peroxide residue detector

Isingeniso

Indwangu encibilikisiwe inezici zosayizi omncane we-pore, i-porosity ephezulu kanye nokusebenza kahle kokuhlunga, futhi iyisisekelo sokukhiqizwa kwemaski.Leli thuluzi libhekisela ku-GB/T 30923-2014 plastic Polypropylene (PP) Special Material Encibilikisiwe, elungele i-polypropylene njengento eluhlaza eyinhloko, ene-di-tert-butyl peroxide (DTBP) njenge-ejenti yokunciphisa, i-polypropylene encibilikisiwe impahla ekhethekile.

Izindlela isimiso

Isampula liyancibilika noma livuvukele ku-toluene solvent equkethe inani elaziwayo le-n-hexane njengezinga langaphakathi.Inani elifanelekile lesixazululo lamuncwa i-microsampler futhi lafakwa ngokuqondile ku-chromatograph yegesi.Ngaphansi kwezimo ezithile, ukuhlaziywa kwe-chromatographic yegesi kwenziwa.Izinsalela ze-DTBP zinqunywe indlela yangaphakathi evamile.

Imishini eyinhloko nama-reagents

1) I-chromatograph yegesi, i-Capillary column inlet, umtshina we-FID,

2) Hlaziya ibhalansi

3) Ikholomu ye-Capillary: AT.624 30m*0.32mm*1.8μm,

4) Isoftware yeChromatographic workstation,

5) I-N-hexane, i-chromatographic ehlanzekile;

6) I-Di-tert-butyl peroxide, ehlanzekile ngokuhlaziya;

7) I-Toluene, ihlanzekile yokuhlaziya.

I-GC-7890 Gas chromatograph isebenzisa isistimu yokulawula ikhompuyutha encane kanye nesibonisi sesikrini esikhulu sesiShayina, ukubukeka kuhle kakhulu futhi kubushelelezi.Okhiye abasanda kuklanywa bekhibhodi balula futhi bayashesha, futhi amasekhethi ayizingxenye ezingenisiwe, ngakho ukusebenza kwezinsimbi kuzinzile futhi kuthembekile.

Ukusebenza isici

Ⅰ、Ukuhlanganiswa kwesekethe ephezulu, ukunemba okuphezulu, imisebenzi eminingi,

1, ukhiye we-All-microcomputer key, 5.7 inch (320*240) isibonisi esikhulu se-LCD ngesiShayina nesiNgisi, isibonisi sesiShayina nesiNgisi singashintshwa ngokukhululeka, ukuze kuhlangatshezwane nezidingo zamaqembu ahlukene abantu, inkhulumomphendvulwano yomshini womuntu, kulula ukuyisebenzisa. .

2, I-Microcomputer ilawula i-hydrogen flame detector ukuze kuzuzwe umsebenzi wokuthungela okuzenzakalelayo, uhlakaniphe kakhulu.Isekethe entsha yedijithali ehlanganisiwe yedijithali, ukunemba kokulawula okuphezulu, ukusebenza okuzinzile nokuthembekile, kufika ku-0.01℃ ukunemba kokulawula izinga lokushisa.

I-3, umsebenzi wokuvikela igesi, vikela ikholomu kanye nephuli ye-thermal conductivity, umtshina wokubamba ama-electron.

Inomsebenzi wokuzixilonga ekuqaliseni, okwenza abasebenzisi bazi ngokushesha imbangela kanye nesimo sokuhluleka kwensimbi, umsebenzi wesitophuwashi (isilinganiso sokugeleza esilula), ukugcinwa kokwehluleka kwamandla kanye nomsebenzi wokuvikela, umsebenzi wokuphazamisa ukuguqulwa kwamandla, ukuxhumana kwedatha yenethiwekhi. kanye nomsebenzi wokulawula kude.Umsebenzi wokuvikela izinga lokushisa elingaphezulu uqinisekisiwe

Ithuluzi alilimele futhi linesistimu yememori yedatha engadingi ukusetha kabusha konke.

Ⅱ、Umklamo oyingqayizivele wesistimu yomjovo, ingaba umkhawulo wokutholwa ophansi

1. Umklamo wembobo womjovo oyingqayizivele wokuxazulula ukucwaswa komjovo;Umsebenzi wesinxephezelo sekholomu ekabili awuxazululi kuphela ukukhukhuleka komugqa wesisekelo okubangelwa izinga lokushisa elihleliwe, kodwa futhi ususa umthelela womsindo ongemuva ukuze uthole umkhawulo wokutholwa ophansi.

2, Ngekholomu egcwele, uhlelo lomjovo we-capillary shunt/non-shunt (nomsebenzi wokuhlanza i-diaphragm)

I-3, i-othomathikhi ezenzakalelayo/i-manual gas injector enendlela eyisithupha, i-headspace injector, i-thermal resolution injector, i-methane converter, i-automatic injector.

Ⅲ、Izinga lokushisa elihleliwe, ukulawulwa kwezinga lokushisa kwesithando somlilo okunembile, ukuzinza okusheshayo

1, izinga lokushisa elingumugqa wama-oda ayisishiyagalombili lihleliwe, ngemva komnyango kusetshenziswa idizayini yokushintshanisa yesithombe kagesi, enokwethenjelwa futhi ihlala isikhathi eside, ihlakaniphile ngemva kwevolumu yomoya eguquguqukayo yesistimu yomnyango, finyeza uhlelo ngemva kokukhuphuka/ukwehla kwesikhathi sokulinganisa esizinzile sesistimu yomtshina, qaphela ngempela ukusebenza okuseduze kwezinga lokushisa legumbi, ukunemba kokulawula izinga lokushisa kuka-±0.01℃, kuhlangabezana nezidingo zohlaziyo olubanzi.

2, Ivolumu enkulu yebhokisi lekholomu, isistimu yomnyango wangemuva ohlakaniphile ongenasinyathelo ivolumu yomoya eshintshashintshayo ngaphakathi nangaphandle, finyeza uhlelo ngemva kokuphakamisa/ukupholisa uhlelo lomtshina oluzinzile lwebhalansi;Isistimu yesithando somlilo: izinga lokushisa elizungezile +5 ℃ ~ 420 ℃

I-3, Umphumela wokufakelwa ungcono: ibhokisi lekholomu, ukuhwamuka, ukutholwa kungamadigri angu-300, ibhokisi elingaphandle kanye nekhava eliphezulu lingaphansi kwama-degree angu-40, kuthuthukisa izinga lokuhlola, ukuqinisekisa ukuphepha komsebenzisi.

4, Idizayini eyingqayizivele yegumbi lokuhwamuka, umthamo omncane ofile;Ukushintshwa kwezinsiza: iphedi lomjovo, i-liner, i-polarizer, umqoqi, umlomo wombhobho ungashintshwa ngesandla esisodwa;Ukushintsha umzimba oyinhloko: ikholomu yokugcwalisa, isampula ye-capillary kanye nomtshina kungasuswa ngokuphelele ngesikrufu kuphela, ukusinakekela kalula.

Ukuzwela okuphezulu, umtshina wokuzinza okuphezulu, ukuhlangabezana nezidingo zezinhlelo ezahlukene

Umtshina we-Hydrogen flame ionization (FID), umtshina we-thermal conductivity cell (TCD), umtshina wokubamba ama-electron (ECD),

Umtshina we-Flame Photometric (FPD), umtshina weNitrogen kanye nePhosphorus (NPD)

Zonke izinhlobo zamadetectors zingalawulwa ngokuzimela izinga lokushisa, umtshina we-hydrogen flame kulula ukuwuhlakaza nokuwufaka, kulula ukuwuhlanza noma ukuwushintsha umbhobho.
