# Daily English Learning of Analytical Instrument # Topic: High-Performance Liquid Chromatography (HPLC)-3 ¿ÆÑÐÒÇÆ÷Ó¢Óï¿ÚÓïÿÈÕÒ»Á·¡ª¡ªÒºÏàÉ«Æ×£¨Èý£© This is oral English of analytical instrument organized by EWG1990 English group. Welcome to lesson 6. Today we will cover the third and final part of High-Performance Liquid Chromatography£¨HPLC£©. Now let's begin the part 1£º ☞ Vocabularies: 1. ÏìӦʱ¼ä relative response 2. УÕýÒò×Ó correction factor 3. ÏàËÆÏàÈÜÔÔò rule of similarity 4. ×îС¼ì²âŨ¶È minimum detectable concentration 5. Íâ±ê·¨ external standard method 6. ÔëÐÅ±È noise-signal ratio 7. ·å¿í peak width 8. ÎïÀí¶Û»¯·¨ physical deactivation 9. УÕýÇúÏß·¨ calibration curve method 10. Ìå»ýÅÅ×èÉ«Æ× size exclusion chromatography 11. Äڱ귨 internal standard method 12. ¶þ¼«¹ÜÕóÁмì²âÆ÷ diode-array detector£¬DAD 13. ±ê׼ƫ²î standard deviation Now let's begin the part 2£º ☞ Sentences: 1.
