Hydrocarbons in the Mediterranean Sea: Their Occurrence and Fate in the Sediment and in the Water Column, as Dissolved and Associated with Small and Large Size Particulates

Hydrocarbons have been analysed by capillary gas liquid chromatography and HPLC/UV spectrophotometry. Hydrocarbons are present essentially in a dissolved form in the water column (for more than 90% for samples collected below 1,000m) and associated with small-size particles.

Developments in the Determination of Organophosphorus Pesticides

Despite of the progress made, there is still a further need for procedures which reduce handling time, e.g. by automation, and/or increase specificity of the HPLC determination in matrices of practical interest, such as food, animal and human tissues and environmental samples.

Analysis of Water-Soluble Acidic Compounds Derived from Spilled Oil in a Controlled Marine Enclosure

A liquid-liquid extraction procedure was developed in order to obtain acidic and basic-neutral compounds. Water-soluble acidic fraction was analysed after methylation by gas-chromatography on capillary columns coated with either SE-52 or PEG-20 M.

Trace Enrichment and HPLC Analysis of Chlorophenols in Environmental Samples, Using Precolumn Sample Preconcentration and Electrochemical Detection

The chlorophenols have been eluted from the precolumn on an analytical column (5?m LiChrosorb RP-18, 12.5 cm ? 4 mm) by use of a switching valve system followed by separation. Detection was carried out with an electrochemical detector.

Disappearance of Dislodgable Residues of Methomyl from Leaves and Vegetables in Tamilnadu (India

The dislodgable residues of methomyl from leaves and vegtables were determined by a single-step methanol extraction followed by reversed-phase HPLC. The residues on the bhendi vegetables and leaves were several times higher than on the brinjal vegetables and leaves.

Analysis of vanillylmandelic and homovanillic acids in urine using solid phase sample preparation and high pressure liquid chromatography with electrochemical detection

pid, simple and specific method for quantification of vanillylmandelic acid (VMA) and homovanillic acid (HVA) in urine is described. The method is suitable for routine use and may include other organic acids in human urine.

Purification of an onco-fetal antigen from mammary carcinoma cells

SummaryMammary carcinoma cell membranes were solubilized by a zwitterionic detergent, 3-(3-cholamidopropyl)-dimethyl-ammonio)-propanesulfonate (CHAPS). The solubilized membrane components were resolved by high pressure liquid chromatography (HPLC) using a styrogel protein column.

Polycyclic Aromatic Hydrocarbons in Rock Oysters: A Baseline Study

Coral-rock oysters were collected in September 1982 from six locations in the area of Mermaid Sound in North-Western Australia. Analysis was carried out by digestion of the samples, followed by solvent extraction and analysis of the extracts using HPLCUVF and GC-MS.
