3.Chitsime cha ion

Gwero la inerceramic ion ion limatsimikizira kuti zinthu zowunikira sizingasangalatse pa gwero la ion pakagwiritsidwe ntchito kwanthawi yayitali, kukulitsa moyo wautumiki.;

Mapangidwe amitundu iwiri, kugwiritsa ntchito kusinthana kukulitsa nthawi yosinthira ulusi;

Chigamulo chowoneka cha mawonekedwe ogwirira ntchito a filament kudzera pa doko loyang'ana ma filament;

Mtundu wa gwero la ion: Gwero lamphamvu la Electron (EI)

Kusintha kwa gwero la ion: gwero la inert ceramic ion, kusintha kwa mapulogalamu awiri a filament

Filament panopa: 0-500μA

Mphamvu ya ionization: 5-100 eV

Kutentha kwa ion: 50 ℃-350 ℃

Okonzeka ndi zenera kuonerera filament kuti zowoneka kuweruza mmene ntchito ulusi

Kutentha kwa mawonekedwe:50-350 ℃

4.Quality analyzer

Quality analyzer: yokhala ndi mwatsatanetsatane zitsulo zonse za quadrupole ndi pre quadrupole

The quadrupole ndi wokometsedwa kulamulira kutentha, amene angathe kuonetsetsa khalidwe bata zizindikiro popanda kufunika kulamulira kutentha

Pre quadrupole detachable ndi wachable kupewa kuipitsidwa kwa quadrupole waukulu

The quadrupole yakonza ukadaulo wa ion mphamvu, yomwe imakulitsa liwiro la ayoni kudutsa mu quadrupole ndikuwongolera mawonekedwe azizindikiro.

5. Chowunikira

Kutalika kwa moyo wautali 13 omwazika dynodeekuchulukitsa kwa ma lectronic

Okonzeka ndi 10kV kutembenuza dynode ndi makina a mandala ochotsa phokoso losalowerera ndale

6.Vacuum system

Pompa siteji yakutsogolo,liwiro≥4 m³/h

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

Kuchuluka kovomerezeka kwa magawo a chromatographic5 ml / mphindi (Iye)

Configured ndi otentha cathode ionization vacuum gauge, ndi mapulogalamu akhoza mwachindunji kuwerenga mkulu vacuum kuwerenga.

7.Gawani / osagawanika jekeseni

Kutentha kwakukulu kogwiritsa ntchito: 450˚C

Njira yoyendetsera gasi: kuthamanga kosalekeza, kuthamanga kosalekeza, pulogalamu mmwamba/pansikupanikizika, pulogalamu yopita mmwamba/pansi, jekeseni wa pulse

Kupititsa patsogolo pulogalamu / kukwezedwa kwakanthawi:10 oda

Makanidwe osiyanasiyana: 0-1035 kPa (0-150 psi)

Zolemba malire splitratio:9999.9:1

Fmalo otsika0-200 mL / mphindi (N₂)

Fmalo otsika0-1000 mL/mphindi (H₂)

8.Uvuni wazambiri

Opaleshoni kutentha osiyanasiyana:kutentha kwachipinda: +4˚Cku450˚C

Kulondola Kuyika kwa Kutentha:0.1˚C

Tkulondola kwa ulamuliro wa mlengalenga:0.01˚C

Kutentha Kukhazikika: ≤0.5%

Tkufanana kwa mlengalenga: ≤2.5%

Kukhudzidwa kwa chilengedwe: Kutentha kozungulira kukasintha ndi 1˚C, kuposa 0.01 ℃

Kutentha Mtengo::≥100˚C /min

Programmed Heating Repeatability: ≤1%

Dongosolo la Kutentha Lokonzedwa: 32

Nthawi Yozizira(kuyambira 450 ℃ mpaka 50 ℃): ≤4 min

Nthawi Yothamanga KwambiriNthawi: 9999.999 min

• Kutentha kwakukulu kwa magetsi a RF kumatha kusintha bwino malo osiyanasiyana a labotale, ndipo magwiridwe antchito a zida amakhala okhazikika;
• Mkulu mwatsatanetsatane onse zitsulo quadrupole, kuonetsetsa kusamvana bwino;
• Quadrupole mass analyzer yokhala ndi pre quadrupole, quadrupole ili ndi mphamvu zotsutsana ndi kuipitsa;
• Electronic multiplier yokhala ndi dynode yosinthira mphamvu kwambiri, kuonetsetsa kuti tili ndi chidwi kwambiri;
• Kutenga pampu yamagetsi ya turbo yogwira ntchito kwambiri, yothamanga kwambiri komanso kuthamanga kokhazikika, kuonetsetsa kuti chilengedwe chizikhala chosasunthika chanthawi yayitali cha misa spectrometry;
• Kutentha kwambiri kwa inert gwero la ion kuli ndi mphamvu zambiri za ionization, kumachepetsa kuipitsidwa, ndipo kumakhala ndi ma filaments apawiri, kupereka kawiri nthawi yogwiritsira ntchito;
