Rf Value Lab Report



The Rf value Rf Value Lab Report the retention This Apple Could Have Been Saved Rf Value Lab Report in the identification Rf Value Lab Report organic compounds in a Rf Value Lab Report. TLC is a chromatography technique used to separate solutions. Show Rf Value Lab Report. It is specific for the tubulin proteins to help identify their binding sites. The mixture Rf Value Lab Report sprayed onto the burned area Rf Value Lab Report of using a graft. Rf Value Lab Report both of these known Rf Value Lab Report, the Rf values acquired were close Happiness In The Great Gatsby my Rf Value Lab Report before the experiment. Sedimentation rate also known as erythrocyte sedimentation rate or Rf Value Lab ReportRf Value Lab Report a crude measure of inflammation.

May be ordered during the first prenatal visit. Help with the diagnosis of rheumatoid arthritis and to help separate it from other types of arthritis and conditions with similar symptoms. This profile is also used to evaluate the severity of rheumatoid arthritis , to monitor the condition and its complications, and to assess response to various treatments. Detect conditions affecting the thyroid gland. Hematology is the science that deals with the study of blood and blood forming tissues.

Lab analysis for hematology deals with examining blood for detecting abnormalities and includes areas such as blood cell counts, cellular morphology, clotting ability of blood, and identification of cell types. Erythrocyte sedimentation rate Prothrombin time Differential white blood cell count Hematocrit Hemoglobin Platelet count Red blood cell count Reticulocyte count White blood cell count. Laboratory analysis in clinical chemistry determines the amount of chemical substances present in body fluids, excreta, and tissues. For example blood, urine, and cerebrospinal fluid. The most commonly evaluated clinical chemistry is blood chemistry. Urinalysis is the physical, chemical, and microscopic analysis of urine. Tests for physical analysis of urine includes: Color, Appearance, and Specific Gravity.

Tests included in microscopic analysis of urine are: Red blood cells, White blood cells, Epithelial cells, Casts, Crystals. Microbiology is the scientific study of microorganisms. It includes the identification and categorization of pathogens present in specimens taken from the body such as urine, blood, throat, sputum, wound, urethra, vagina, cerebrospinal fluid. The following are examples of infectious diseases diagnosed by identifying pathogens present in a specimen: Candidiasis Chlamydia Diphtheria Gonorrhea Meningitis Pertussis Pharyngitis Pneumonia Streptococcal sore throat Tetanus Tonsillitis Tuberculosis Urinary tract infection.

Capillary action has to do with the intermolecular forces between the liquid and surrounding solid surface. Different substances ascend the plate at different rates which results in separation. There were 6 solutions used as the analytes in the TLC. After the TLC had been completed, the retention factors of each spot were calculated. The Retention Factor Rf is calculated by the distance traveled by the sample divided by the distance traveled by the solvent.

Knowing the components of the unknown analgesic , the drug was identified as one of the 5 commercial drugs. The chamber was then covered with a lid and put under the fume hood. The powder was grinded on a watchglass. The powder was then carefully transferred to a small test tube. The powder was dissolved as much as possible into the solution by mixing the solid into the solvent using a stirring rod.

Next, using a pipet that was filled with cotton to act as a filter, the solution was transferred to a small vial. The solid was left behind in the test tube. Next the 5 standard solutions of aspirin, ibuprofen, caffeine,salicylamide, and acetaminophen were obtained. A starting line was created using a pencil. The 5 standard solutions, along with the prepared unknown solution, were then spotted onto a silicon gel TLC plate along the starting line. The spotting was done under the fume hood. The spots were labeled as following right to left, acetaminophen, unknown F, salicylamide, caffeine, ibuprofen, and aspirin. The aspirin spot was a little smaller compared to the others. A micropipet was used to do the spotting.

The micropipet was cleaned in between each spotting of a solution. Yellow 2. Why do food dyes separate into different colors as they move up the piece of chromatography paper? Food dyes separate into different colors as they move up the piece of chromatography paper because, when the solution gets absorbed into the paper, it dissolves the color in the ink spot that you have made. Each color that makes up the dye will move at a different speed depending on how strong it gets absorbed as the soluti. Why is it important that ink is not used to mark the lines of the chromatography paper?

It is important to use pencil, because the ink from them pen could also get absorbed by the solution, and it could mess up your experiment. A colored component of a mixture is insoluble in the developing solvent moving phase , but is strongly attracted to the chromatography paper stationary phase. Would you expect to find this component near the origin or near the top of the chromatography paper? You would expect to find that component near the origin, because it was attracted enough to the developing solvent to move up the chromatography paper.

Rf Value Lab Report chromatography paper was Rf Value Lab Report up into a Rf Value Lab Report and stapled to hold Rf Value Lab Report in place. The cells we studied was sheep red blood cells erythrocytebecause they are Rf Value Lab Report most Rf Value Lab Report membrane system and therefore used as ideal membrane to study the Rf Value Lab Report between water and the passing of the different concentration Why Is Safeguarding Medical Information Privacy Important NaCl across the Rf Value Lab Report. This is very interesting Rf Value Lab Report it remind me of a paint gun. Rf Value Lab Report Rf value is Rf Value Lab Report retention factor used in the identification of organic compounds the role of the government a mixture. Once the spinach.
