Calibration

Turbidity: - Turbidity is a degree of water clarity. Turbidity is defined as an “expression of the optical property that causes light to be scattered and absorbed rather than transmitted in straight lines through the sample”. Nephelometers are used to measure the intensity of light scattered by contaminants present in water such as suspended and colloidal solids like clay, silt and microscopic organisms. Turbidimeters using the principle of nephelometer compare the light scattered due to…

Electrophoresis; Separation of Proteins Purpose: To create an electrophoresis gel in order to further separate Cytochrome C, Myoglobin, Albumin and Hemoglobin(proteins) based off of their net charges. Materials: • Rabbit hemoglobin • Serum albumin(cow) • Myoglobin • Cytochrome C • Microtubes • Tape • Micropipets • Agarose gel • Buffer • Gel chamber • Test tubes • Test tube holders • Gloves • Macropipets Properties of Proteins: Protein Color Isoelectric Point Net Change at pH 8.6 Cytochrome C…

The Egyptian her The last seven years in Egypt were similar to a hopeless aged disease for the equality between men and women in the Arab world. Although women had a vital role in the Arab spring, they still struggle for the basic rights to live. In fact, this problem threatens many standards in a young woman’s dreams and visions of becoming an important person in life. Gender inequality against women is an actual major issue in Egypt and it’s nothing new when talking about the Egyptian flooding…

the supplies are needed: 1. The bun toaster. a. This machine takes 20 minutes to heat up and provided the correct toasting of buns when calibrated correctly. If it is calibrated incorrectly, the best thing to do is look up how to adjust the calibration in the user manual. 2. The HLZ or heated landing zone. a. This machine also takes 20 minutes to heat up. It is where all the sandwiches go after being assembled in the kitchen. This area keeps the…

Abstract As one of the most popular analgesic and antipyretic, especially for pregnant women and children, acetaminophen is available over the counter in many forms. When consumed over long periods of time or in high dosages, acetaminophen has serious side effects including liver damage and other organ damages, therefore an effective quality control method of analysis. Here a method using cyclic voltammetry to analyze the concentration of acetaminophen in a liquid suspension Publix brand…

The objective of the present study is to isolate piperine from the black pepper. Our attempt was to extract the piperine with petroleum ether from black pepper and isolation using the same solvent. It is very difficult to extract and isolate the piperine using a non-polar solvent like petroleum ether due to solubility. During our study, we observe that piperine have a very little solubility in the petroleum ether, at the same time the solubility of the resinous material in petroleum ether is…

Determination of Isoprenaline Hydrochloride Concentration Using Ultra Violet/ Visible Spectroscopy and Quantification of Sodium and Potassium Using Flame Spectroscopy Introduction In UV/VIS (ultraviolet-visible light) spectroscopy, light absorption as a function of various wavelengths gives data about electronic transitions within a solution [1]. The electronic transitions involve exciting an electron from one principle quantum state to another by the absorption of energy [2]. A change in…

Raju Chandra et al; A reliable and reproducible reversed-phase high performance liquid chromatography (RP-HPLC) was developed for the quantitative determination of quetiapine fumarate from marketed bulk tablets. The active ingredient of quetiapine fumarate separation achieved with C18 column using the methanol water mobile phase in the ratio of 30:70 (v/v). The active ingredient of the drug content quantify with UV detector at 359 nm. The retention time of quetiapine fumarate is 5.27 min. A good…

The overall objective of this lab was to verify Bernoulli-Euler beam theory for the lip-loaded cantilever and use that to calculate the Poisson ratio for the material in this case 6061-T6 aluminum. This was done by having to different objectives for each part of the Lab. Part one was use electrical resistance strain gage, this was to measure the strain a cantilever beam as it undergoes a known deflection. We would then compare the measurements with that of the strains predicted by simple beam…

sample. • Instrumentation: This speaks to problems or issues that might occur with the instrument or the way the researcher is measuring the dependent variable. This could arise as a result a several reasons like using different instruments or calibration issues…
