1 This technical support retention time lock.

2 One cause of retention time uncertainty identified is poor oven temperature repeatability.

3 Conclusion:Retention time and affection time of aconite alkaloids after used with thunberg fritillary bulb omni-alkaloids were longer than these before matching.

4 Remark: the substance 2,6-Di-tert-butyl-4-methylphenol (BHT) must show a retention time smaller than 16 minutes.

5 Primary chromatographic evaluation showed that the retention time of the model solutes increased with the increase of the phenylglycine unit.

6 Identification of retention time can be accurately obtained using a pentane peak as a standard.

7 By using this graph, we can predetermine the retention time, exiting temperature or the humidity drop of the drying process easily.

8 The hydraulic retention time can effectively effect the efficiency of photocatalytic degradation of thin films.

9 Drawing ink strokes as heavy makeup, retention time shift between the vast Sun Yun, mood slowly quiet despair. Painted scroll to be formerly quiet residual color yellow.

10 The body weight, body temperature, mean retention time of chyme in digestive tract, gastric emptying velocity, gastrin and motilin levels, and visceral index of mice.

11 The effects of hydraulic retention time, reactor structure, sludge inoculation concentration and carrier size on biofilm formation on carrier surface in an internal loop biofluidised bed were studied.

12 Objective To study retention time of endogastric stomach tubes in 84 patients with a-cute cerebrovascular diseases.

13 The experiment system is designed, including the process scheme, equipment structure and retention time control.

14 Poor injection technique is also iden tified as a cause of retention time variability.

15 Owing to relative high concentration of lactose in milk or adulterated milk, lactose peak was very broad and spread to retention time corresponding to sucrose and raffinose.

16 Using the program chromatogram can be drawn in CRT screen and the screen displays retention time in every top peak.

17 Dual - point formula is suitable for the correction of nonlinear shift and retention time delay.

18 Method a documented procedure was established to define the controls needed for the identification, preservation, protection, retrieval, retention time and disposition of general records.

19 In common state, the effect of solvent ingredient always exists in the first part of retention time of two-way data, such as HPLC-DAD and GC-MS etc.

20 Remember that early peaks will be more influenced by poor equilibration than later ones. Determine if the variation in retention time is acceptable (generally, less than 0.05 min).

21 Based on the quasi-linear relation between peak width at half-height and retention time, a new measure of column efficiency-real peak number (RPN) was developed.

22 On this basis, a 12 - hour settling zone retention time is recommended for most applications.

23 Results To determine the Oridonin extracted from diethyl ether of plasma by RP-HPLC method, the retention time was stable, the linear curve fitted well,(www.Sentencedict.com) and the results were accurate and reliable.

24 The inflaming retarding effect of Ca on molten Al-Mg alloy under various temperatures and retention time is investigated.

25 In production process of carbon fiber, appropriately increase preoxidation retention time will be propitious to the performance of carbon fiber.

26 The rate of passage of digesta through the digestive tract, which is best described by the mean retention time, is an important measure of gut function.

27 The number of heterotrophic bacteria and nitrifying bacteria increased with the time of the hydraulic retention time, contrary to the nitrobacter.

28 The four purified squalene synthase used to catalyzed the substrate FPP. Then the catalysate squalene were detected by GC-MS analysis method with the 18.44 retention time (RT).

29 The fingerprints of Shenmai injection was established by HPLC, and the relative retention time and peak area ratio of each common peak was determined.

30 Nevertheless , steric hindrance caused by chemical structure reduces the retention time.
