Jyn Yynn and Wai [267] chelated organoarsenic compounds with sodium bis (trifluorethyl) dithiocarbamate prior to application of high performance liquid chromatography. He applied the technique to mixtures of arsenite, arsenate, dimethylarsonic acid, dimethylarsinic acid and other organoarsenic compounds. 

Bermejo-Barrera, P., Moreda-Pineiro, J., Moreda-Pineiro, A., Bermejo-Barrera, A. Selective medium reactions for the arsenic(III), arsenic(V), dimethylarsonic acid and mono-methylarsonic acid determination in waters by hydride generation online electrothermal atomic absorption spectrometry with in situ preconcentration on Zr-coated graphite tubes.

Cacodyl and its derivatives are now mostly of historical interest. One derivative, cacodylic acid [dimethylarsonic acid, (CH3)2As02H], and its sodium salt, are commercially available and are widely used as herbicides. 

Slejkovec et al. [125] used HPLC-atomic fluorescence to separate and quantify the anionic arsenic compounds found in urban aerosol samples. The initial sample preparation produced aqueous extracts. These were found to contain only arsenate, although the separation worked for mixtures of arsenite, arsenate, monomethylar-sonic acid, and dimethylarsonic acid. The detection limit for arsenate was 80 pg mL . ... 

Measurement of alkylated forms— Very often the natural form of an element can be toxic, although its alkylated form is relatively harmless, or vice versa. A good example of this is the element arsenic. Inorganic forms of the element such as As (111) and As (V) are toxic, whereas many of its alkylated forms such as monomethylarsonic acid (MMA) and dimethylarsonic acid (DMA) are relatively innocuous. ...
