Thyroxine and thyroxine glucuronide were separated on a C]8 Ultrabase column (4.6 mm X 250 mm, 10 p.m). Solvent A was a 35 65 (v/v) mixture of methanol and 20 mM potassium phosphate buffer (pH 7.0) containing 1% triethylamine. Solvent B was methanol. A linear gradient from 0 to 100% B was run in 15 minutes. Elution was completed by maintaining 100% B for 5 minutes. Two methods of on-line radiochemical detection was used liquid scintillation using a 2 mL detection cell, and solid scintillation using lithium scintillator glass in an effective cell volume of 400 p-L. The latter method was most convenient.

The density of sulfur is close to that of lithium chloride. The volume of solid sulfur formed in reaction (11.9) is less than 16% of the overall volume of solid products. Sulfur dioxide formed in reaction (11.9) is rather soluble in electrolyte, so that the intrinsic pressure in the cells is enhanced negligibly. Despite this, the cases of thionyl chloride-lithium cells are made to be rather strong and the extreme corrosion activity of thionyl chloride enforces application of high-alloy steels or nickel. Sintered glass-metal pressure seals are used in thionyl chloride-lithium cells, same as in cells with some other systems.

The dye sensitised semi-conductor electrode is a transparent conducting sheet of glass coated (5 pm) with nanocrystalline TiOj (diameter 20 nm) doped with a ruthenium bipyridyl complex. The dye absorbs light, becomes excited and injects electrons into the TiOj electrode. The electrons travel into the transparent WO3 hhn and then, to balance the charge, lithium ions from the electrolyte solution insert into the WO3 and in so doing create the coloured species as described above. If the light source is removed then the cell is bleached back to its original colour. However, if the... 

Reagent grade anhydrous lithium bromide powder (Matheson, Coleman and Bell) was used after drying in a vacuum oven at 100°-120°C. Potassium chloride (Fisher certified ACS) was dried at 110°C and used to calibrate the conductance cell. Deionized water from the laboratory supply was piped directly into a Pyrex glass still (Corning model AG-la) and distilled into a polyethylene vessel, where it was kept until needed. The specific conductance of the water was 1 X 10 6 12 1 cm-1. 

There are reports on the preparation of lithium electrodes in which Li wires [17,23-25] and Li rods have been embedded in glass or plastic materials, and fresh Li surfaces have been prepared in solutions by shearing off the edges of the metal [17,23,24], An example of such an approach was noted in the discussion on the construction of various cells. It should be mentioned that the plastics that can be used with metals such as lithium are highly pure (low plasticizer content) polyethylene and propylene.
