the goal was to find the moles of NaOH‚ as well as a 0.1 molarity‚ while in the second week to goal was to determine the percent KPH in the sample. The first week titrations were successful and had very similar amounts of pink‚ which shows the precision of the results. The best trials were in the sample trial and the second and third trials. The average molarity calculated for the first week was 0.1017 M. This very close to the 0.1 M that was supposed to be made. The standard deviation in the average

0 ml/ min and effluents were monitored at 255 nm. The retention times of chlorpheniramine maleate and phenylephrine were found to be 3.13 min and 4.58 min‚ respectively. The method was validated in terms of linearity‚ range‚ specificity‚ accuracy‚ precision‚ limit of detection (LOD) and limit of quantitation (LOQ). The linearity for both the drugs was found in the range of 10-70 μg/ml. The % recoveries of chlorpheniramine maleate and phenylephrine were found to be between 101.09 and 98.99. The

LM35 Precision Centigrade Temperature Sensors The LM35 series are precision integrated-circuit temperature sensors‚ whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35 thus has an advantage over linear temperature sensors calibrated in ˚ Kelvin‚ as the user is not required to subtract a large constant voltage from its output to obtain convenient Centigrade scaling. The LM35 does not require any external calibration or trimming

For Acidic hydrolysis‚ SAC was found to be well susceptible to acid hydrolysis with 0.05 M HCl at 40 ˚C for 30 min caused about 8% reduction in the peak area of SAC (Fig.4a). While this mild condition didn’t affect VAL. While‚ nearly 27% was the reduction in SAC’s peak area when subjected to alkaline hydrolysis. This considerable decline in the peak area of SAC when subjected to 0.01 M NaOH at 40°C for 30 min revealed degradation products peaks appeared at 3.339 and 9.482 minutes (Fig.4b) and they

Pendulum From Wikipedia‚ the free encyclopedia For other uses‚ see Pendulum (disambiguation). "Simple gravity pendulum" model assumes no friction or air resistance. A pendulum is a weight suspended from a pivot so that it can swing freely.[1] When a pendulum is displaced sideways from its resting equilibrium position‚ it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. When released‚ the restoring force combined with the pendulum’s mass

justify measurements in terms of accuracy and precision. From these solutions can errors be also known and calculated‚ thus are also prevented and minimized in the process. Measurement uncertainty arises from the lack of knowledge of how sure or accurate a measurement is. This produces a non- negative variation of results which can be compared from a true and accepted value. Accuracy refers to how close a measurement is to its accepted and real value while precision is defined as how different separate

different statistical tools is available‚ some of them simple‚ some complicated‚ and often very specific for certain purposes. In analytical work‚ the most important common operation is the comparison of data‚ or sets of data‚ to quantify accuracy (bias) and precision. Fortunately‚ with a few simple convenient statistical tools most of the information needed in regular laboratory work can be obtained: the "t-test‚ the "F-test"‚ and regression analysis. Therefore‚ examples of these will be given in the
