Title: Process for determining very small quantities of herbicides based on triazine compounds.
Inventor: AFFONSO ALVARO
IPC: G01N25/14
Filed: 1990-08-24
Abstract: The invention relates to a simple and rapid process for determining very small quantities of herbicides based on triazine compounds, especially atrazine, simazine and propazine. Here, a sample of the substance to be examined is extracted with an organic solvent which is insoluble or soluble with difficulty in water, an aqueous pyridine solution is added and heat is then applied. After cooling, a concentrated aqueous alkaline solution of the same volume as that of the pyridine solution is added and the u/v spectrum of the reaction product obtained in the separated pyridine layer is measured in the range from 400 to 200 nm. The sensitivity of the indication for atrazine at 355 nm, for example, is in the range from 0.0001 to 0.001 mg/l. Instead of extraction with the organic solvent, the herbicide contained in water may be subjected to solid-phase extraction.

Abstract: The method relates to the field of metallurgy and can be applied in the conductive heating of billet-type metallic material for the purpose of surface treatment, for example to coat it with a lubricating agent. The object of the invention is to avoid the thermal damage to the material surface which normally occurs in conductive heating as a consequence of spark formation or local overheating and to markedly reduce the wear on the current-carrying parts of the system. For this purpose, the contact points between the material to be conductively heated and the parts of the system which are to carry the current are wetted with an electrolytic liquid containing dissolved or dispersed solids. The depositable substances in the liquid are deposited as a thin solid layer on the material surface by drying immediately after leaving the contact point.

Date Aug. 22, 1991.A well fluid sampling tool and method for retrieving single-phase hydrocarbon samples from deep wells. The sampling tool is lowered to the required depth, an internal sample chamber is opened to admit well fluid at a controlled rate, and the sample chamber is then automatically sealed. The well fluid sample is immediately subjected to a high pressure to keep the sample in its original single-phase form until it can be analyzed. The sample is pressurized by a hydraulically-driven floating piston powdered by high-pressure gas acting on another floating piston. Once sampling is initiated, e.g. by an internal clock, the entire sequence is automatic. Also disclosed is a sample transfer container for securing the pressurized sample from the tool and maintaining it in single-phase form during transport to an analytical laboratory. This invention avoids the disadvantages arising from phase separation of hydrocarbon well fluid samples.
