- LV 11283 IZGUDROJUMA FORMULA 1. Process interesējošo daļiņu, kuru molekulārā masa ir no 1 līdz 1000 kDa, atdalīšanai no maisījuma, kas atšķiras ar to, ka šo daļiņu molekulārā masa ir mazāk kā desmit reizes lielāka vai mazāka par citu maisījuma daļiņu molekulāro masu un šajā procesā ietilpst maisījuma filtrēšana ar tangenciālās plūsmas metodi caur filtrējošo membrānu ar tādu poru izmēriem, kas nepieciešami, lai atdalītu interesējošās daļiņas no maisījuma un uzturētu filtrācijas plūsmas līmeni 5 līdz 100% diapazonā no plūsmas pārejas punktā, līknes apgabalā, kurā transmembrālais spiediens ir atkarīgs no plūsmas, tādējādi panākot vajadzīgo daļiņu selektīvu izdalīšanu no maisījuma.
- 2. Process saskaņā ar 1. punktu, kas atšķiras ar to, ka transmembrālo spiedienu uztur pēc būtības nemainīgu gar membrānu uz līmeņa, kas nav lielāks par transmembrālo spiedienu filtrācijas pārejas punktā.
- 3. Process saskaņā ar 1. punktu, kas atšķiras ar to, ka plūsmas lielums ir no 50 līdz 100% no plūsmas vērtības pārejas punktā.
- 4. Process saskaņā ar 1. punktu, kas atšķiras ar to, ka plūsmas lielums ir no 75 līdz 100% no plūsmas vērtības pārejas punktā.
- 5. Process saskaņā ar 1. punktu, kas atšķiras ar to, ka maisījums nav atšķaidīts. I
- 6. Process saskaņā ar 1. punktu, kas atšķiras ar to, ka filtrācijā izdalītos paraugus atgriež atpakaļ rezervuārā, kurā atrodas sadalāmais maisījums, un procesu atkārto.
- 7. Process saskaņā ar 1. punktu, kas ir daudzpakāpju process, kurā papildus ietilpst filtrāta filtrēšana otrajā tangenciālās plūsmas filtrācijas stadijā caur membrānu, kurai ir mazāks poru izmērs nekā membrānai, kura tiek izmantota pirmajā riltrēšanas stadijā, un otrās stadijas filtrāta atgriešana atpakaļ pirmajā filtrēšanas stadijā, sakarā ar ko šis process tiek atkārtots.
- 8. Process saskaņā ar 7. punktu, kas atšķiras ar to, ka plūsmas lielums otrajā filtrācijas stadijā ir lielāks par 100% plūsmas vērtību pārejas punktā. 2
- 9. Process saskaņā ar 8. punktu, kas atšķiras ar to, ka abas filtrēšanas stadijas ir ultrafiltrēšanas stadijas.
- 10. Process saskaņā ar 7. punktu, kurā papildus ietilpst otras filtrēšanas stadijas filtrēta filtrēšana trešajā tangenciālās plūsmas filtrēšanas stadijā caur filtrēšanas membrānu, kurai ir mazāks poru izmērs nekā tas ir otrai membrānai, un trešās filtrēšanas stadijas filtrēta atgriešana atpakaļ uz pirmo filtrēšanas stadiju, sakarā ar ko šis process tiek atkārtots.
- 11. Process saskaņā ar 10. punktu, kas atšķiras ar to, ka plūsmas lielums trešajā filtrēšanas stadijā ir lielāks par 100% plūsmas vērtību pārejas punktā.
- 12. Process saskaņā ar 11. punktu, kas atšķiras ar to, ka visas trīs filtrēšanas stadijas ir ultrafiltrēšanas stadijas.
- 13. Process saskaņā ar 1. punktu, kas atšķiras ar to, ka transmembrālais spiediens pazeminās filtrēšanas procesam virzoties uz priekšu.
- 14. Process saskaņā ar 1. punktu, kas atšķiras ar to, ka transmembrālais spiediens paliek aptuveni nemainīgs, filtrēšanas procesam virzoties uz priekšu.
- 15. Process saskaņā ar 1. punktu, kas atšķiras ar to, ka interesējošās daļiņas ir bioloģiski objekti, ko izvēlas no grupām, sastāvošām no proteīniem, polipeptīdiem, aminoskābēm, koloīdiem, mikoplazmām, endotoksīniem, vīrusiem, ogļhidrātiem, RNS un DNS.
