| titleOfInvention | A detection method for extractable metal ions in a rubber piston |
| abstract | The invention discloses a detection method for extractable metal ions in a rubber piston. Step 1: preparing extraction media with different pH and different polarities; step 2: extracting, adding 10 mL of different extraction media to each rubber piston sample , placed in a suitable container, sealed, placed in a high-pressure steam sterilizer, kept at 121 °C for 1 h and then lowered to room temperature, or ultrasonically extracted at 30 °C for 1 h to obtain the extract, and the extract was tested; the same method was used to prepare a blank extract ; Step 3: Detect, adopt inductively coupled plasma (ICP) method, and measure the content of metal ions according to the intensity of characteristic spectral lines of different metal ions. The method of the invention has high detection precision and good repeatability, and the method is simple, safe and convenient for laboratory operation. |
