Concering 134a, there is both pharma grade 134a and “technical grade” R 134a(industrial grade r134a).
Erinevus on järgmine:
HFA raketikütused / aerosoolkütused HFA -134 A & nbsp; meditsiinilisteks pihustiteks, sealhulgas:
* & nbsp;MDIs (Metered Dose Inhalers) also known as pharmaceutical aerosols or asthma sprays for the treatment of asthma, COPD (Chronic Obstructive Pulmonary Disorder) and respiratory infections
* ninaspreid allergilise riniidi raviks
* vahtpihustid
* suukaudsed ja paiksed pihustid (nt närvi sensibiliseerimine, hammaste elujõud, valu leevendamine)

CFC 11, CFC 12 and CFC 114
mida kasutatakse traditsiooniliselt meditsiinilistes pihustites, mis on Montreali protokolli kohaselt järk-järgult kasutuselt kõrvaldatud osoonikihti kahandavate hüdrofluoroalkaanidega HFA 134a, mida nimetatakse ka farmaatsiatoodete HFA - 134A (P) & nbsp;
While“Technical grade” R 134a(industrial grade r134a) is predominately used as refrigerant R134a and fire extinguishing agents .It is with:
*the higher purity obtained by additional manufacturing processes specifically developed and applied to meet & nbsp;the stringent specifications set out for & nbsp;pharmaceutical grade products,
*manufacturing in dedicated facilities & nbsp;according to the current good manufacturing practice guidelines,
* kõrgetasemeline - kvaliteedikontroll, kasutades analüütilisi meetodeid, mis on spetsiaalselt välja töötatud & nbsp; sõelutakse rohkem kui 60 lisandit & nbsp; raketikütused madalamal kui üks osa & nbsp; miljoni kohta,
* registration of the manufacturing & nbsp;processes and quality control systems according to the standards for drug & nbsp;active substances, although both Propellant Hfa (P) 134a for Inhaling and Spray Gas with DMF Certificate & nbsp;klassifitseeritakse kui
exipients. & nbsp;
