Tannic acid (TA) is a natural, non-toxic organic acid with corrosion inhibitive property for metals and alloys. A chemiluminescence (CL) system of KIO4 (potassium periodate)–H2O2 (hydrogen peroxide)–Tween40 has been employed in the detection of tannic acid in industrial wastewater. Tannic acid hydrolyzes to form mainly glucose and gallic acid. Its astringent property is due to the presence of polyphenolic groups.

Caution

At room temperature, concentrations over approximately 70% in water tend to form 1-2% thioglycolides per month, which hydrolyze to the original free compound when made acid or alkaline. The 70% solution oxidizes in air, but is stable at room temperature when tightly closed. Thioglycolate salts may also lose purity on storage. The exclusion of air does not materially improve stability.

4×25 mL in Sure/Seal™
The 25 mL Sure/Seal™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.

Novel metal oxide/phosphonate hybrids were formed from titanium(IV) isopropoxide in a two-step sol-gel process. Starting material for barium-strontium-titanate thin films. Used to make porous titanosilicates, potential ion-exchange materials for cleanup of radioactive wastes. Applied in the formation of a heterosupermolecule consisting of a TiO2 nanocrystallite-viologen electron acceptor complex whose light-induced electron transfer has been demonstrated.
Commonly used as a precursor for the preparation of Titania (TiO2)

For the preparation of N- and O-trifluoroacetyl derivatives of a wide range of biologically active compounds for GC analysis. Also used in the oxidation of aldehydes to acids, esters, or amides. Trifluoroacetic anhydride can undergo reaction with deoxyguanosine in pyridine to give the corresponding 6-substituted-2-deoxyguanosine derivatives. It can also react with urea-hydrogen peroxide complex to generate peroxytrifluoroacetic acid, which can convert aldoximes to nitroalkanes.

The TSKgel® HXL column line consists of eight columns with different pore sizes, TSKgel G1000HXL through TSKgel G7000HXL, and three columns with an extended linear range of the calibration curve, TSKgel GMHXL, TSKgel GMHXL-L and TSKgel MultiporeHXL-M. The calibration curves are shown to the right. Main characteristics are: ultra-low sample adsorption, i.e., the columns show true size exclusion behavior for most polymers, maximum operating temperature for TSKgel HXL-type columns is 60°C for G1000HXL, G2000HXL, G2500HXL and G3000HXL, and 80°C for the remaining columns in the product line. See TSKgel HHR HT columns for operating temperatures of 140°C, the columns are shipped in THF, which can be exchanged for a limited number of organic solvents. TSKgel HXL-type columns are conventional GPC columns with column dimensions of 7.8mm ID x 30cm.

Compatibility

TSKgel® SuperMPHZ-H Guard Column 821886

Tosohs innovative multi-pore technology is now also available in 3, 4 and 6 micron TSKgel® SuperMultiporeHZ columns and guard columns. Three columns, varying in linear range, are available. The base material of each TSKgel SuperMultiporeHZ column is poly(styrene/divinylbenzene). Particles in TSKgel SuperMultiporeHZ columns and guard columns are mono-disperse in size and exhibit a broad range of pore sizes. Each particle, by design, has an extended linear calibration curve, thereby greatly diminishing the presence of inflection points in chromatograms.

Column can only be used in THF solvent.
