Laboratory use specifications and test methods GB/T 6682 Analysis3 Method summaryThe sample remaining in the clavulanic acid with pH6.0 Tris (Tris) buffer - acetonitrile extraction, dichloromethane - n-hexane Liquid-liquid partition purification, molecular sieve ultrafiltration, liquid chromatography - mass spectrometry/mass spectrometry detection and confirmation, external standard.4 Reagents and materialsUnless otherwise specified, the reagents used were of analytical grade water as a water line with GB/T 6682 regulations. 4.1 Methanol. HPLC grade. 4.2 acetonitrile. HPLC grade. 4.3 dichloromethane. 4.4 n-hexane. 4.5 acidic alumina. 4.6 Tris (Tris). 4.7 hydrochloric acid. 5mmol/LTris of 4.8 pH6.0 buffer solution. Weigh 0.61gTris (4.6), was dissolved with about 900mL of water (4.7) adjusted with hydrochloric acid pH value 6.0, set the volume to 1000mL 4.9 clavulanate potassium (clavulanicacidpotassium, CAS number. 61177-45-5) standards, the purity of not less than 99%. 4.10 standard stock solution, 5000mg/L. Weigh 59.5mg potassium clavulanate (equivalent to 50mg clavulanic acid) standard (4.9), (4.8) dissolved 5mmol/LTris pH6.0 buffer solution of a small amount, and then acetonitrile (4.2) and dilute to 10mL volumetric flask, at -30 ℃ Stored. 4.11 intermediate standard solution, 5mg/L. lessons 0.1mL standard stock solution (4.10) in 100mL volumetric flask, dilute to engraved with acetonitrile Degrees, mix well to prepare a 5mg/L standard intermediate solution, the standard solution for an extemporaneous preparation prior to analysis. 4.12 standard solution. according to the sensitivity and the need to use the blank matrix extract the intermediate standard solution (4.11) diluted to Standard Operating Solution, the standard solution for immediate use. Matrix blank extract of clavulanic acid-free blank samples obtained after extraction by 7.1 steps. 4.13 ultrafiltration tube with molecular weight of 30,000 molecular sieves. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of SN/T 2488-2010_English be delivered?Answer: Upon your order, we will start to translate SN/T 2488-2010_English as soon as possible, and keep you informed of the progress.
