Bincike na musamman na plasticizer na kwakwalwan filastikGas chromatographyGC-7900 ne mafi inganci bincike kayan aiki, kayan aiki da microcomputer iko, keyboard-tushen aiki, LCD allon Sinanci menu nuni. Tare da high lantarki layi hadewa, inganci mai kyau, aiki mai sauki, ƙwaƙwalwar ajiya saiti sigogi, ba tare da buƙatar sake saita kowane lokaci, daidaita da dogon lokaci aiki. Babban shafi akwatin, babban fan tare da atomatik bayan bude ƙofar sanyaya tsarin inganta sanyaya gudun shafi akwatin, da gaske cimma dakin zafin jiki + 5 ℃ aiki. Kayan aiki iya sassauci amfani da capillary ginshike, gilashi ginshike, bakin karfe ginshike. Za a iya yin thermostat da kuma tsari dumama aiki.

Dedicated kayan aiki saiti na kwakwalwa filastik fim: Host + FID + capillary ginshike samfurin.

Gas chromatographer GC-7900 kayan aiki siffofin:

1, kayan aiki amfani da LCD kasar Sin nuni, aiki yanayin a duba daya bayyane, farawa ba buƙatar sake saita sigogi, sauki da kai tsaye.

2, kayan aiki taɓa maɓallin shigarwa, tare da aikin kulle keyboard, don hana kuskuren aiki daga rushewa yanayin amfani da kayan aiki na al'ada.

3, kayan aiki daban-daban iska hanyoyin sarrafawa, sarrafa bawul daidaito high, sake dubawa mai kyau, zai iya tasiri tabbatar da daidaito a kowane bincike.

4, kayan aiki dukan aikin na'ura da kwanciyar hankali, iya daidaitawa da dogon lokaci ba tare da katsewa aiki, nazarin lokaci gajeren, nazarin inganci high.
