1.5.2.5 Detectors The detectors used in UPLC should be able to handle very fast scanning methods because half-height peak widths of less than one second are usually obtained with columns packed with 1.7 µm particles. The detector must be able to give high sampling rate adequate to capture enough data points across the peak for an accurate and reproducible integration of analyte peak. The dispersion (volume) of the detector flow cell must be minimal to maintain separation efficiency. Conceptually

this experiment is to extract and find quantitative amount of Beta-carotene from a carrot sample. The raw product(carrots) was extracted using simple distillation. The purity of the product will be characterized using percent yield‚ thin layer chromatography‚ Beer’s Law‚ and UV-vis. Beer’s law is used because in this experiment we are comparing our extraction of B-Carotene to the Stock B-Carotene. Beer’s law shows that absorbence of light at a specific wavelength is proportional to the concentration

that may have been missing in an excavated skull would be the perpendicular plate‚ vomer‚ and middle and inferior nasal concha. Hassan can tell the age of the remains by sutures such as coronal‚ safittal‚ lambdoid and squamous. A male’s vertebral column is on average about 28 inches‚ where as a female’s would be around 24 inches. The bone most likely affected by strangulation other than the cervical vertebrae would be the hyoid bone. You could compare size and shape of the vertebrae. Cervical

specific and accurate reverse phase high performance liquid chromatographic method was developed for the simultaneous determination of chlorpheniramine maleate and phenylephrine in tablet dosage forms. A reversed-phase C-18 column (250 mm × 8 mm i.d.‚ particle size 10 µm) column with mobile phase consisting of acetonitrile and phosphate buffer 55:45 (v/v) (pH 5.6 ± 0.02‚ adjusted with triethylamine) was used. The flow rate was 1.0 ml/ min and effluents were monitored at 255 nm. The retention times

experiment is to identify an unknown proprietary drug using thin-layer chromatography. The unknown’s behavior in thin-layer chromatography will be compared with that of its possible component analgesics. The possible unknowns and their analgesic ingredients will be Anacin (aspirin‚ caffeine)‚ Excedrin (acetaminophen‚ caffeine‚ aspirin)‚ Motrin (ibuprofen)‚ and Tylenol (acetaminophen). Introduction Thin-layer Chromatography(TLC) was the method used to figure out and identify the drug. TLC is done

the Kool-Aid was correct. However‚ solely based upon the Rf values‚ the dyes in the green Kool-Aid are Red 40 and Yellow 6 as those are closet Rf value to the numeric data collected and calculated from the Kool-Aid chromatogram. However‚ the chromatography paper in both trials display that the dyes in Kool-Aid are a form of yellow and a form of blue because one color band was of a blue tint and the other‚ a yellow tint. Therefore‚ based on this qualitative data‚ the dyes in the green Kool-Aid are
