Njira zojambulira: kusanthula kwathunthu, kuyang'anira ma ion osankhidwa, kusanthula kwathunthu ndi kuyang'anira ma ion osankhidwa motsatizana, kusanthula mosinthana.

3. Gwero la Ion

Gwero la ceramic ion lopanda mphamvu limaonetsetsa kuti zinthu zowunikira sizimamatira pa gwero la ion panthawi yogwiritsidwa ntchito kwa nthawi yayitali, zomwe zimawonjezera moyo wautumiki. ;

Kapangidwe ka ulusi wawiri, kugwiritsa ntchito mosinthana kuti kuwonjezere nthawi yosinthira ulusi;

Kuweruza kowoneka bwino momwe ulusi umagwira ntchito kudzera mu doko lowonera ulusi;

Mtundu wa gwero la ayoni: Gwero la mphamvu ya electron (EI)

Yokhala ndi zenera lowonera ulusi kuti liwone momwe ulusiwo ukugwirira ntchito

Kutentha kwa mawonekedwe: 50-350℃

4. Chowunikira khalidwe

Chowunikira chapamwamba: chokhala ndi quadrupole yachitsulo yolondola kwambiri yokhala ndi pre quadrupole

Chipinda cha quadrupole chimakonzedwa bwino kuti chizitha kuwongolera kutentha, zomwe zimathandiza kuonetsetsa kuti zinthu zikuyenda bwino popanda kufunikira kuwongolera kutentha.

Chotsukidwa ndi ma quadrupole chisanathe ndipo chikhoza kutsukidwa kuti chisaipitse main quadrupole

Chida cha quadrupole chili ndi ukadaulo wabwino kwambiri wa mphamvu ya ma ion, womwe umathandizira liwiro la ma ion omwe amadutsa mu quadrupole ndikukweza khalidwe la chizindikiro.

5. Chowunikira

Kutalika kwa moyo wautali kwa dynode ya level 13 dispersed dynodendichochulukitsa cha lectronic

Yokhala ndi dynode yosinthira ya 10kV ndi makina a lenzi ochotsera phokoso losalowerera ndale

6. Dongosolo la Vacuum

Pampu ya siteji yakutsogolo,liwiro≥4 m³/h

Konzani pampu ya turbomolecular yogwira ntchito bwino kwambiri，liwiro≥250 L/s

Kuchuluka kwa kayendedwe ka chromatographic column komwe kuloledwa: 5 ml/mphindi (He)

CYopangidwa ndi choyezera cha vacuum cha cathode chotentha, ndipo pulogalamuyo imatha kuwerenga mwachindunji mawerengedwe a vacuum ambiri.

7. Gawani/osagawanitsa injector

Kutentha kwakukulu pogwiritsa ntchito: 450˚C

Njira yowongolera mpweya: kupanikizika kosalekeza, kuthamanga kosalekeza, pulogalamu mmwamba/pansikupanikizika, pulogalamu yoyendera mmwamba/pansi, jakisoni wa kugunda kwa mtima

• Mphamvu yamagetsi ya RF yotentha kwambiri imatha kusintha bwino malinga ndi malo osiyanasiyana a labotale, ndipo magwiridwe antchito a zida ndi okhazikika;
• Kulondola kwambiri kwa zitsulo zonse zinayi, kuonetsetsa kuti pali kusamvana kwabwino ；
• Chowunikira misa ya quadrupole yokhala ndi pre quadrupole, quadrupole ili ndi mphamvu yolimbana ndi kuipitsa;
• Chochulukitsa zamagetsi chokhala ndi dynode yosinthira mphamvu zambiri, chomwe chimatsimikizira kukhudzidwa kwabwino kwambiri;
• Kugwiritsa ntchito pampu ya turbo molekyulu yogwira ntchito kwambiri, yokhala ndi liwiro lalikulu lopopera komanso ntchito yokhazikika, kuonetsetsa kuti malo okhala ndi vacuum yayitali kwa nthawi yayitali a spectrometry yayikulu;
• Gwero la ion lopanda kutentha kwambiri limakhala ndi mphamvu zambiri zoyatsira ion, limachepetsa kuipitsa, ndipo lili ndi ulusi wapawiri, zomwe zimapangitsa kuti nthawi yogwiritsidwa ntchito ikhale yowirikiza kawiri;
• Cyokonzedwa ndi choyezera chokha, chowomba msampha, chowunikira kutentha, choyezera mutu kuti ikwaniritse kusanthula kwa zitsanzo za mayiko osiyanasiyana ；
