O le GC-7890 Gas chromatograph e faʻaaogaina le microcomputer control system ma le faʻaaliga tele o le lau Saina, o foliga vaaia e sili atu ona matagofie ma lamolemole.O ki keyboard fou ua mamanuina e faigofie ma vave, ma o taʻaloga o vaega faʻaulufale mai, o lea e mautu ma faʻatuatuaina le faʻatinoga o meafaigaluega.

Fa'atinoga uiga

Ⅰ、Tu'ufa'atasiga matagaluega maualuga, maualuga sa'o, tele-galuega,

1, All-microcomputer key operation, 5.7 inisi (320 * 240) tele LCD faʻaaliga i Saina ma le Igilisi, Saina ma le Igilisi faʻaaliga e mafai ona fesuiaʻi saoloto, e fetaui ma manaʻoga o vaega eseese o tagata, tagata-masini talanoaga, faigofie ona faʻagaoioia .

2, Microcomputer pulea hydrogen flame detector e ausia ai galuega faʻafefete otometi, sili atu le atamai.Fa'akomepiuta fa'akomepiuta fou tu'ufa'atasi, maualuga fa'atonuga sa'o, mautu ma fa'atuatuaina fa'atinoga, e o'o atu i le 0.01 ℃ fa'atonuga o le vevela.

3, galuega puipuia kasa, puipuia le koluma ma le vaitaele conductivity vevela, electron puʻeina detector.

O loʻo i ai le galuega o le suʻesuʻeina o le tagata lava ia i luga o le amataga, lea e mafai ai e tagata faʻaoga ona vave iloa le mafuaʻaga ma le tulaga o le faaletonu o meafaifaʻaili, galuega taofi (fuaina o le tafe lelei), le faʻaogaina o le eletise ma le puipuiga, galuega faʻalavelave faʻafefe-mutation, fesoʻotaʻiga faʻamatalaga fesoʻotaiga. ma galuega fa'atonutonu mamao.O le galuega puipuia o le overtemperature ua mautinoa

E le'o fa'aleagaina le meafaigaluega ma e iai se faiga e manatua ai fa'amaumauga e le mana'omia ai fa'atonu uma.

Ⅱ、Injection faiga mamanu tulaga ese, e mafai ona maualalo tapulaa iloa

1. Tulaga tulaga ese mamanu uafu e foia tui faailoga tagata;E le gata ina foia e le koluma fa'alua le fa'agasologa o le tafega o laina fa'avae e mafua mai i le vevela o lo'o fa'apolokalameina, ae fa'apena fo'i ona to'ese ai le fa'aosoina o le pisa i tua ina ia maua ai se tapula'a maualalo.

2, Faʻatasi ai ma koluma faʻapipiʻiina, faʻaogaina o le capillary shunt / non-shunt (faʻatasi ai ma le faʻamamaina o le diaphragm)

3, Filifiliga otometi/manual kasa ono-ala injector, headspace injector, vevela fofo injector, methane liliu, injector otometi.

Ⅲ、Temperature polokalame, sa'o le ogaumu pulea vevela, mautu vave

1, E valu-poloaiga laina vevela ua faapolokalameina, ina ua uma le faitotoa e faaaoga photoelectric ki contactless mamanu, faatuatuaina ma umi, atamai ina ua uma le faiga faitotoa stepless voluma ea fesuisuiai, faapuupuu le polokalama ina ua mavae le tulai mai / mataua o le faiga detector taimi paleni mautu, iloa moni lava. le fa'aogaina o le vevela o le potu, fa'atonu le sa'o o le vevela o le ± 0.01 ℃, fa'afetaui mana'oga o le tele o su'esu'ega.

2, Tele voluma o le pusa koluma, atamai pito i tua faiga stepless fesuiaiga ea voluma i totonu ma fafo, faapuupuuina le polokalama ina ua uma ona sii i luga / cooling le faiga detector taimi paleni mautu;Faiga ogaumu fa'avevela: vevela ambient +5 ℃ ~ 420 ℃

3, E sili atu le aafiaga insulation: o le pusa koluma, vaporization, iloa e 300 tikeri, o le pusa fafo ma le pito i luga faavaa e itiiti ifo i le 40 tikeri, faaleleia le fua faatatau faataitai, ia mautinoa le saogalemu o le tagata e faaaogāina.

4, Fuafuaga tulaga ese o le potu vaporization, laiti le tele oti;Suiga mea fa'aoga: tui tui, liner, polarizer, aoina, fa'asuisu e mafai ona sui i le lima e tasi;Suiga o le tino autu: faʻatumu koluma, capillary sampler ma detector e mafai ona aveese atoa ma naʻo se faʻaoga, faigofie tausiga.

Faʻalogo maualuga, faʻamautu maualuga, faʻafetaui manaʻoga o polokalame eseese

Su'esu'e fa'ama'i afi (FID), su'esu'ega fa'ameaola (TCD), su'esu'e pu'e eletise (ECD),

Su'esu'e Ataata Mu (FPD), Su'e Nitrogen ma Fofofo (NPD)

O ituaiga uma o detectors e mafai ona tutoʻatasi pulea le vevela, hydrogen flame detector e faigofie ona disassemble ma faʻapipiʻi, faigofie ona fufulu pe sui le nozzle.
