六、校正：校正是保证仪器测试精度的重要措施，本仪器必须按下列三项校正指

Sixth, the correction: <br>Correction is an important measure to ensure the accuracy of test instrument, the instrument must be corrected according to the following three indicators, according to the pharmacopoeia calibrated once every six months. <br>1, the accuracy of the sample volume <br>(1), material <br>balance (accuracy 0.01 g); distilled water; 150ml beakers <br>(2), the operation <br>1, turn on the instrument. <br>2, will be poured into a beaker of distilled water (about 2/3) on the specimen stage product, then the stirrer should be placed outside the sample cup. <br>3, the whole point of the channel keys to set the sampling 5ml, as measured by mean volume of 5ml ± 2% as acceptable, the computer To adjust the required calibration <br>accuracy of 2, the particle count (calibration) <br>Example: ≥10μm correction channel <br>1, standard particle: peak particle should be less than 10μm ± 0.5μm; <br>2, peak two channels should be more than 90% of the total particle; <br>3, dilution: 1000-1500 grain /ml(0.9% sodium chloride injection or clean water). <br>4, the correction method: When the instrument is powered self test is complete, the instrument has been tested for environmental compliance purified water, the particles dilutions standard 10μm force flip back and forth 20 times to a uniform particle distribution, taking

Six, correction:<br>Correction is an important measure to ensure the accuracy of the instrument test, the instrument must be in accordance with the following three correction indicators, according to the Pharmacopeia every six months.<br> 1, the accuracy of the sampling volume<br>(1, equipment)<br> Balance (0.01 g accuracy); distilled water; 150ml beaker<br>(2), operation<br>1, power on the instrument.<br>2. Pour distilled water into the beaker (about 2/3) on the inspection table, at this time the agitator should be placed outside the sampling cup.<br>3, point full channel key, set sampling 5 ml, such as the measured volume average of 5 ml to 2% qualified, if you need to adjust the need to use a computer calibration<br>2, the accuracy of particle count (calibration)<br>Example: Correction of the channel of s10 m<br>1, the standard particles: the peak particle size should be within 10 m to 0.5 m;<br>2, the two main peak path should account for more than 90% of the total number of particles;<br>3, dilution concentration: 1000-1500 grains /ml (0.9% sodium chloride injection or clean water).<br>4, correction method: When the instrument is plugged in to complete the self-test, the instrument has been purified water environmental test in accordance with the requirements, the standard particle dilution of 10 m will be turned back and forth 20 times, so that the particle distribution is uniform, take

Vi. correction:<br>Calibration is an important measure to ensure the test accuracy of the instrument. The instrument must be calibrated once every half a year according to the following three calibration indexes and pharmacopoeia.<br>1. Accuracy of sampling volume<br>(1) equipment<br>Balance (accuracy 0.01g); distilled water; 150ml beaker<br>(2) operation<br>1. Power on the instrument.<br>2. Pour distilled water into the beaker (about 2 / 3) and place it on the inspection table. At this time, place the mixer outside the sampling cup.<br>3. Click the full channel key and set 5ml for sampling. If 5ml ± 2% of the measured volume is qualified, the computer shall be used for calibration if necessary<br>2. Accuracy of particle count (calibration)<br>Example: ≥ 10 μ M channel correction<br>1. Standard particle: the peak particle size should be within 10 μ m ± 0.5 μ m;<br>2. The two main peaks should account for more than 90% of the total number of particles;<br>3. Dilution concentration: 1000-1500 capsules / ml (0.9% sodium chloride injection or clean water).<br>4. Calibration method: when the instrument is powered on to complete self inspection, and the purified water environment test has been conducted by the instrument, turn the diluent of 10 μ m standard particles back and forth forcefully for 20 times, so that the particles are evenly distributed, take<br>
