| titleOfInvention | A kind of method that hf etching capillary prepares quartzy needle |
| abstract | The present invention relates to a kind of methods that new hydrofluoro acid etch capillary prepares quartzy needle.Specifically the polymer coating of capillary position to be etched is removed, then which is fixed on to the device (Fig. 1) of design, certain volume hydrofluoric acid is added, capillary is performed etching, until capillary etching fracture.The volatilization of hydrofluoric acid and affinity interaction with quartz surfaces make quartz capillary etching position form tapered surface.This method can be widely applied for the preparation that mass spectrum EFI needle, genetic engineering injection needle etc. need to control the quartz material of outer diameter and the conical surface. |
