A collector (1) and method for collecting samples of liquid from at least one source of liquid for automated analysis of the samples. The collector has at least one receptacle (3) for receiving liquid from the source of liquid and holding a quantity of the liquid for obtaining a sample. Each receptacle (3) has an inlet (17) for delivery of liquid from the respective source of liquid and an open top sized to admit the sample collection device into the receptacle. The collector also has a spillway (7) in fluid communication with the open top of the receptacle for receiving excess liquid spilling over the open top of the receptacle (3). The collector is constructed so that liquid continuously flows through the collector. A drain (11) of the collector receives liquid from the spillway for draining the liquid from the collector.

Collector for an automated on-line bath analysis system

The invention is a tracer method for online monitoring of downhole zonal contributions of oil, condensate, gas, or water mass flux of a production flow in a petroleum production well, comprising arranging distinct tracer carrier systems, each in different production zones in said well, said distinct tracer carrier systems arranged for releasing unique tracers to a fluid of said production zones, said tracers having affinity after downhole release to separate phases of oil, condensate, gas, or water, using an online tracer monitor, conducting sampling of tracer concentrations for at least one of the tracers in said zonal mass fluxes at a high sampling rate, based on said concentration values, estimating the corresponding zonal tracer fluxes for each delivery data point and using said one or more estimated zonal mass fluxes to control one or more Petro Technical processes.

A testing system for continuous sampling and testing of effluent at a water treatment plant, the system comprising: a sampling system to collect samples of the effluent; a monitoring system (40) connected to the sampling system, for measuring environmental parameters of the samples, the monitoring system comprising: a first analysis chamber (41) for measuring environmental parameters of at least two selected from the group consisting of: pH, oxidation reduction potential (ORP) value for state of reduction oxidation (Redox), conductivity value for total dissolved solids (TDS), dissolved oxygen (DO), turbidity (Tu) value for suspended solid (SS) and temperature (T); a second analysis chamber (50) for measuring the concentration of anions in the samples using a plurality of ion selective electrodes (ISEs); and a third analysis chamber (61) for measuring the concentration of heavy metals in the samples using anode stripping voltammetry (ASV); and a control system to control the collection of samples by the sampling system, to control washing and rinsing of the analysis chambers, and to record the measurements obtained by the monitoring system.

A water quality testing system

A process for determining the concentration of trace alkali or alkaline earth metal impurities in a silicon wafer cleaning solution which is maintained in continuous flow through a bath (8). The process comprises continuously delivering from the flow of cleaning solution a portion of that solution into and through a sample cell (1). A sample of the solution is then withdrawn (41) and analyzed (4) in order to determine the concentration of trace alkali, alkaline earth or transition metal impurities in the cleaning bath solution. Additionally, a comparison may be made between the concentration of impurities in the cleaning solution and an empirically determined correlation, in order to determine if the concentration of impurities on a silicon wafer surface exceeds about 1 x 1010 atoms/cm2.

Provided are a method of and an apparatus for formulating a multicomponent drug capable of surely making a multicomponent drug meeting criteria for productization with high accuracy into a product. The method and apparatus obtain a chromatogram from an extract or a base of a multicomponent drug, evaluate whether the base meets the criteria for productization based on the obtained chromatogram with high accuracy, and subject the base determined in the high-accuracy evaluating as an accepted one meeting the criteria to dosage form processing, to produce a formulated drug having a given dosage form. The high quality evaluation is realized by performing peak assignment of a target fingerprint obtained from a chromatogram to a reference fingerprint with high accuracy.

Method of and apparatus for formulating multicomponent drug

The invention relates to an apparatus for continuously sampling and analyzing a liquid effluent, e.g. from an industrial installation, thereby permitting the rapid detection of pollution in a discharge. The apparatus comprises a valve (6) for permanently deflecting part of the liquid effluent to be analyzed in the direction of first distribution valve (12), at least two provisional storage tanks (10), connected to the inlet of a sampling cell (22), and capillary tube (28) for taking a sample from said sampling cell (22) and passing it to at least one measuring device (30). The distribution valve (12) is designed so as successively to fill provisional storage tanks (10), the storage tanks (10) being emptied, in the order in which they were filled, into the sampling cell (22) when the latter is empty.

Apparatus for the continuous sampling and analysis of a liquid effluent

A device for continuously sampling and analysing a liquid effluent, e.g. from an industrial plant. A device enabling rapid detection of pollutants in waste is provided. The device comprises a unit (6) for constantly diverting a portion of the liquid effluent to be analysed towards a first distribution unit (12), at least two temporary storage vessels (10) connected to the inlet of a sampling cell (22), and a unit (28) for removing a sample from said sampling cell (22) and feeding it to at least one measuring apparatus (30). Said first distribution unit (12) is designed to fill the empty temporary storage vessels (10) one after the other, which vessels (10) are then emptied into the empty sampling cell (22) in the order in which they were filled.

Device for continuously sampling and analysing a liquid effluent

L'invention concerne un dispositif concu pour effectuer le prelevement en continu et l'analyse d'un effluent liquide, issu, par exemple, d'une installation industrielle. Le but de l'invention est de realiser un dispositif permettant de deceler rapidement une pollution dans un rejet. Ce but est atteint a l'aide d'un dispositif comprenant: des moyens (6) pour detourner en permanence une partie de l'effluent liquide a analyser en direction de premiers moyens de distribution (12); au moins deux recipients de stockage provisoire (10), relies a l'entree d'une cellule de prelevement (22); des moyens (28) pour prelever un echantillon dans ladite cellule de prelevement (22) et le diriger vers au moins un appareil de mesure (30), lesdits premiers moyens de distribution (12) etant concus pour remplir successivement un recipient de stockage provisoire (10) vide, ces recipients (10) etant vides dans l'ordre ou ils ont ete remplis, dans ladite cellule de prelevement (22) lorsque celle-ci est vide.
