Report abuseTranscript of Paper Chromatography Lab DataPaper Chromatography Lab By: Priyanka Das, Riju Patra and Tiffany TangPurposeTo use paper chromatography to separate a mixture of metallic ions in solution, thus using the position and color of the spot produced by each ion to determine the ions present in the unknowns. ProceduresIn this lab, samples of 5 different cations are placed on chromatography paper, along with a known mixture, which is a mixture of the 5 cations, and 4 unknown substances. The paper was then placed in eluting solution, which is a mixture of HCL, ethanol, and butanol, and t

Only numerical techniques of https://prezi.com/apnhflnwy_ea/paper-chromatography-lab/ on-line or off-line measurements associated with data handling by computer can be used. From their very nature numerical techniques are discontinuous and the number of experimental points is limited. According to information theory this discontinuous character does not imply a loss of accuracy provided that some simple relationship derived from the theory of sampled systems is http://link.springer.com/article/10.1007/BF02270542 fulfilled. These conditions deal with the choice of the sampling frequency, the frequency band-width of the amplifier and measurement system, and the upper limit of the signal frequency. We have made a theoretical and an experimental study of these phenomena and the results allow us to derive some simple rules which make the choice of parameters of the system of data acquisition easy. We have also determined the main sources of error in data acquisition systems and calculated their contribution.Literature[1] Guiochon, G., Goedert, M., Jacob, L., Gas Chromatography 1970, R.
