Calibration

recorded by placing each sample into the calibrated Spec-20 spectrophotometer. Transmittance was found by dividing percent transmittance by one hundred. The absorbance value was calculated using the equation A=-log(T) and was graphed to create a calibration…

Interaction of concentrated nitric acid and sulfuric acid generated nitronium ion which is electrophile. And methyl benzoate nitration is one of electrophilic aromatic substitution. Nitronium ion will reacts with protonated intermediate at the meta position. After NO2 substituted, it becomes arenium ion intermediate. Then, the remained product HSO4- will attack hydrogen then transfer the proton to methyl 3-benzoate. In the experiment, students placed around 12 drops of concentrated H2SO4 in…

Abstract: Hemoglobin is an iron-containing protein in red blood cells that enable the red blood cell to bind oxygen in the lung and transport the oxygen to tissues and organs throughout the body. Oxygen binds reversibly to these iron atoms and is carried throughout the blood. As part of the experiment, we computed the concentration of hemoglobin and iron in a crystalline blood sample by measuring the absorbance of the sample as methemoglobin and cynamethemoglobin at 450-650nm. Furthermore, the…

Introduction: LC-MS is used for the bioanalysis of small molecules drugs, which has molecular mass of less than 800 Da. Now a days, it is also frequently used for the bioanalytical determination of biopharmaceuticals.1 In pharmaceutical R & D, it takes a year to develop a new marketing drug identified from thousands of new compounds. The drug discovery is divided into early and late phase, during which pharmacokinetics study or bioanalysis of a drug is done. Once, the bioanalysis of a drug is…

because of cost savings. Other than function as a place to relax for families, mobile home decks useful to protect the family from flooding or disruption from wild animal, viewed from the concept that makes the distance between the ground and the calibration of the…

I. Research Question What monetary policy should be adopted in order to maintain price stability when the government uses the supply side fiscal policies? II. Brief Introduction Monetary and fiscal policies today majorly focus on the demand stimulus by incentivizing consumption in order to increase the aggregate demand to achieve higher output. Even though consumption contributes to the major output, purely focusing on the demand side typically only provides a short run solution to economic…

analyzed to evoke TEOAEs. HFT measurements were obtained using a Madsen Otoflex 100 diagnostic immittance device coupled to a laptop. Before each session of testing, the diagnostic immittance device was calibrated using an inbuilt 2-ml cavity. After calibration, a probe tip inserted into the participant’s ear canal with the probe in the vertical position while the participant’s head was in a face sideways position. After the test, the participant’s head was turned faced up and the probe was in…

Let’s start the introduction by talking about our main target, Escherichia coli or how it is mostly unknown, E.coli, are a diverse and large group of bacteria found food, the environment, and in the intestinal tracts of humans and animals were it normally inhabits and it can also cause infection in other parts of the body, especially the urinary tract. Its name was given by a German physician called Theodor Escherich and it is the most common member of the genus Escherichia. E.coli is “a…

period of time. The system provides trainings on product, procedures and the quality of the customer service. After the trainings the Buddy gives recommendations to the new Agent and controls average talk time after making together multiple call calibrations and discussing the previous conversations. It also makes the Team Leader work much easier as now they have to spend only 10-15% of time with the…
