The progress of the reaction was monitored in my case using two TLC plate. It first started off with the spotting of Standard benzoin and benzil which were provided in the lab and followed by the addition of the reaction mixture at once it starts changing colour/boiling‚ then at 10 and 20 mins into the reflux. Once all the necessary steps were spotted‚ the TLC plate was placed in in a beaker containing CH₂Cl₂(methylene chloride)‚ which was used as the developing solvent in this experiment. To check

A simple‚ precise‚ accurate and rapid High-Performance Thin Layer Chromatographic method has been developed and validated for the simultaneous estimation of of ellagic acid‚ chlorogenic acid‚ gallic acid and quercetin in the leaf extract of Terminalia tomentosa and its Formulation. The stationary phase used was precoated silica gel 60F254.The mobile phase used was a mixture of Butyl acetate: Formic Acid: Distilled Water 14:5:5 (v/v). The detection of spots were carried out at 254 nm. This HPTLC method

These peaks show that the solution in vial 4 contained dichloromethane. This is viable because the column did contain dichloromethane‚ which is what the original 0.70 mL of the bottom layer solution was filtered through. Also the .7 mL of the solution that was ran through the column was a dried dichloromethane solution. The peaks that represented 2-naphthol‚ 1630 cm-1‚ 1364 cm-1‚ and 1216 cm-1‚ also showed that the solution in vial 4 contained

Understanding this reduces the risk of harm to you or the person in you care. The spinal columns made up of individual bones and there are joints that connect these together. A ligament connects bones to support joints ◦ Muscles work like levers and this allows bones at a joint to work like a hinge.The fibres they contain contract which makes

filtration GEL FILTRATION OF PROTIENS Aim: The aim of this experiment is to identify proteins from a complex mixture using the gel filtration technique also known as size exclusion chromatography. This technique is widely used by biochemists when proteins larger than the pores are excluded from the column and the smaller molecules elute last and then collected in test tubes for examination by spectroscopic techniques. The red/brown proteins‚ in particular‚ will be observed closely as they

When people hear that I have scoliosis they generally have a lot of questions‚ or if they know what it is they have to compare me to their aunt’s sister’s dad’s cousin who has it. Scoliosis is not the end of the world‚ but there should be more awareness for it. Scoliosis is defined as: an abnormal lateral curvature of the spine (Scoliosis NP). It can be different for all who have it depending on the degree of the curve or curves‚ and people go through it differently. For me‚ mine was serious enough

Miss Tedo is a 69 year old female who presents with cervical degenerative joint disease. She is seeking physical therapy to help with the limited range of motion due to neck stiffness‚ hypertonicity in her cervical paravertebral muscles‚ postural education‚ and pain reduction. Cervical degenerative joint disease is the wearing down of the vertebral joints at the cervical spine‚ or the neck. There are different possibilities to the pathogenesis of this disease including axial neck pain‚ radiculopathy
