Genderfluid, but I put it through paper chromatography

Aiming at the industrial use of clay column chromatography for optical resolution

A recent study, published in Applied Clay Science, could have applications in clay column chromatography for obtaining enantiomeric compounds in industries. A spherically-shaped particle of synthetic hectorite (denoted as Na-HEC) was ion-exchanged with a divalent Cu(II) complex, [Cu(SS-oxa)]2+ (SS-oxa = SS-2,2′-isopropylidene-bis(4-phenyl-2-oxazoline)). The material is denoted as [Cu(SS-oxa)]2+/HEC. A column for high performance liquid chromatography (HPLC) was prepared by packing 4.0 g of [Cu(SS-oxa)]2+/HEC into a stainless tube (25 cm x 0.4 cm (i.d.)). When tris(acetylacetonato)cobalt(III) (denoted as [Co(acac)3]) was eluted by methanol at the flow rate of 0.2 mLmin-1at 4°C, the compound was separated to D- and L-enantiomers nearly to the baseline.

Chromatography

I tried out (amateur) chromatography today, and my chemistry teacher was right. The colours are so pretty.

Figure 24.7 shows the analysis of a polypeptide hydrolysate by ion-exchange chromatography.

FIGURE 24.7 Analysis of a mixture of amino acids by ion-exchange chromatography using Amberlite IR-120, a sulfonated polystyrene resin. The resin contains phenyl-SO3-Na+ groups. The amino acid mixture is applied to the column at low pH (3.25), conditions under which the acidic amino acids (Asp, Glu) are weakly bound to the resin and the basic amino acids (Lys, His, Arg) are tightly bound. Sodium citrate buffers of two different concentrations and three different values of pH are used to elute the amino acids from the column. Cysteine is determined as cystine, Cy-S-S-Cys, the disulfide of cysteine.

Gas chromatography (GC) in analytical chemistry is a common type of chromatography where the mobile phase is a gas and the stationary phase is separated as a vapour. The instrumentation of gas chromatography is given above picture for more about Gas chromatography

Role of Potency, Purity and Assay in Pharmaceuticals Analysis

Terms like Purity, potency and Assay are widely used in Analytical research and Quality control departments in Pharmaceutical Industries. Analytical Scientists and Quality control Chemists have a lot of confusion related to Purity, potency and Assay. Check out this post to know the answer to the following questions: What is purity? What is potency? What is assay? What are the differences among purity, potency and assay? Read more

Chromatogramm (deutsch: Farbenschreiben) mit Brennnesselblätterextrakt

Auf den unteren Rand eines Löschpapiers wird Brennnesselextrakt aus zerstossenen Blättern aufgetragenen und anschließend in ein mit etwas Spiritus gefülltes Gefäß gestellt.  Die Pflanzenfarbstoffe werden durch die Kapillarkraft nach oben geschwemmt - dadurch werden die verschiedenen Chlorophylle und die anderen Blattfarbstoffe sichtbar. Chlorophylle sind zuständig für die Absorption den Lichts, den Energie- und Elektronentransfer.

Chromatogram with nettle leaf extract

Nettle extract from crushed leaves is applied to the lower edge of a blotting paper and then placed in a vessel filled with a little spirit.  The plant dyes are washed to the top by capillary force - this reveals the various chlorophylls and the other leaf dyes. Chlorophylls are responsible for the absorption of light, energy and electron transfer.

Theoretical Plates chromatography-analytical chemistry

Theoretical Plates chromatography In chromatography, theoretical plates are a fundamental concept used to assess the separation efficiency of a chromatographic column. They play a crucial role in determining the quality and effectiveness of the chromatographic separation. In this section, we will define theoretical plates, explain their significance in assessing separation efficiency, and discuss…

Routine chemical analyses involve determination of the mass percentages of C, H, N and S in a compound, and are often carried out using an automated elemental analyser such as the one shown in the schematic diagram in figure 3.8.

Thin layer chromatography (TLC) is a chromatography principle or technique in analytical chemistry which we used to separate or identify non-volatile mixtures on a small scale. Thin layer chromatography instrumentation is similar to column chromatography. more information about Thin layer chromatography
