Ukuqeda Ukuphahlazeka Kwenalithi kanye Nevolyumu Efile Ekufakeni kwe-Micro-Volume LC/GC (<10 µL)

Ku-metabolomics, i-forensic toxicology, ukuhlukaniswa kwemikhiqizo yemvelo, kanye nokuhlanganiswa kwe-organic trace, ukutholakala kwesampula ephelele kuvame ukukhawulelwa ku-10–50 µL. Ukuphatha lawa ma-micro-volumes kuma-vials ajwayelekile angu-2 mL kudala amaphuzu amabili amakhulu okwehluleka: i-dead volume eningi evimbela i-autosampler ukuthi ingakwazi ukudonsa ama-microliters ambalwa okugcina, kanye nokungahambisani kahle kwenaliti noma ukugoba (ukuphahlazeka kwenaliti) okubangelwa ukushintsha kwama-micro-inserts.
Inalithi ye-autosampler idonsa isampula elincane kusuka esihlanganisini sevayela eliyikhoni lengilazi ukuze kususwe umthamo ongasebenzi

Amaphuzu Abalulekile

  • Imbangela Yokuphahlazeka Kwenaliti:
  • Umsuka Wokulahleka Kwesampula: I-dead volume engu-5–15 µL
  • Isixazululo Sobunjiniyela: Ama-glass micro-vials ahlanganisiwe, ama-conical inserts azilungiselelayo aphakathi nendawo anama-polymer shock springs

Izindlela Zokwehluleka Ekusethweni Kwe-Micro-Volume Vial

I-Insert Exivulekile Ku-Outer Vial ➔ Ukushintsha Kwe-Axis / Ukutsheka ➔ Inaliti Ishaya Umunwe Wengilazi (Ukuphahlazeka/Ukugoba) ➔ Ukuma Kohlelo Lwe-Instrument & Izindleko Zokushintsha Inaliti
Ukushayiswa kwenalithi ye-autosampler okubangelwa ukuxega nokutsheka kwesihlanganisi esiyikhoni esincane ngaphakathi kwevayela ye-chromatography engu-2 mL
  1. Ukususwa Kwe-Insert & Ukuguquka Kokugxila:
  2. Ukukhathala Kwe-Spring & Ukubhoboza Phansi:
  3. Ukuhwamuka kwe-Solvent kanye ne-Void Space:

Ukuqhathanisa: Ama-Loose Inserts vs. Ama-Spring Inserts vs. Ama-Integrated Micro-Vials

Isici
I-Standard Loose Conical Insert
I-Insert ene-Bottom Polymer Spring
I-CHANCEPRO Integrated Fused Micro-Vial
I-Residual Dead Volume
8 – 15 µL
3 – 5 µL
< 2 µL
Ingozi Yokuphahlazeka Kwenaliti
Okulingene nokuphakeme (kungatshazwa)
Okuphansi (kugcwele futhi kumaphakathi)
Uno (kuhlanganiswe unomphela futhi kuqondaniswe)
Ukunemba Kokugxilisa
(ukufakwa okuxekethile)
(ukuqondiswa ngentwasahlobo)
(kuqondaniswe efemini)
Ukuhambisana Ne-Autosampler
Amashalofu ajwayelekile angu-2 mL
Amashalofu ajwayelekile angu-2 mL
Amashalofu ajwayelekile angu-2 mL (Agilent, Waters, CTC)
Umzamo Wokuhlanganisa
Ukufakwa ngesandla okuqondile
Ukufakwa ngesandla okuqondile
Kulungele ukusetshenziswa (ucezu olulodwa)
Umthamo Wesampula Oqondisiwe
> 25 µL
10 – 30 µL
< 10 – 50 µL (amasampula ayigugu)

Izinqubo Ezi-4 Ezingcono Kakhulu Zokujova Okuthembekile Ngaphansi Kuka-10 µL

  1. Setha Ukujula Kokungena Kwenaliti Ngokunembile:0.5–1.0 mm
  2. Khetha Ama-Micro-Vials Ahlanganisiwe Okulandelana Okubalulekile:
  3. Sebenzisa Izintwasahlobo Zepulasitiki Esikhundleni Sezintwasahlobo Zocingo Zensimbi:
  4. Bhangana ne-Ultra-Thin Pre-Slit Septa:

Izixazululo ze-CHANCEPRO Micro-Sampling Chromatography

Kuklanyelwe ukuvikela izinalithi ze-autosampler ezibuthakathaka nokwandisa ukutholakala kusampula enevolumu ephansi kakhulu:
  • I-CHANCEPRO Integrated Fused Micro-Vials (9-425 Screw):
  • Ama-Conical Inserts aqondile azizilungisayo anama-Polymer Feet:
  • Ukuphela kwendawo okungenasici kwe-Ultra-Inert Silanized / Deactivated:
I-CHANCEPRO ihlanganise ingilazi encane yevayela ehlanganisiwe enesihlanganisi esiyikhoni esizilungisayo ukuze kutholakale umthamo ophansi kakhulu wokujova kwe-LC GC
