摘要： The invention is directed to a process analyzing arrangement (10) for continuously determining a water parameter of water (14) of a stationary water site (12), with an automatic analyzer unit (100) and a water sample feed pump (30) for pumping a water sample flow from the stationary water site (12) to the automatic analyzer unit (100),
The automatic analyzer unit (100) comprises:
a physical analyzer (66) with an analyzing chamber (60) where the water parameter is physically determined,
a separate grab sample container (110) of at least 20 ml for collecting a grab sample volume, and
a fluidic control arrangement (200) for selectively directing from the water sample flow an analyzer sample to the analyzing chamber (60) and/or a grab sample to the grab sample container (110),
wherein the fluidic control arrangement (200) comprises an electronic control unit (90) with a grab sampling control (92) and a grab sampling criterion means (94,95,96) for initiating a grab sample action controlled by the grab sampling control (92).
Since the automatic analyzer unit can provide a grab sample, no manual grab sampling is necessary anymore.

摘要： The present invention comprises an optical train (50) and optional wavelength-selective photodetectors. The optical train (50) uses reflecting elements (600) including mirrors and/or prisms to fold the light path of the transmitted UV light beam to direct it through the body (100) of the instrument, through a sample vessel (200) using at least one pass but preferably two or more passes and into illumination contact with a photodetector (400). With each additional pass, the Beer-Lambert path length is effectively increased. Separate second optical train (53) and third optical train (54) exist for the detection and measurement of scattered light by illumination contact with one or more photodetectors.

摘要： A sample handling apparatus/technique/method for a material analyzer, which provides active, variable concentration of a sample, using a measurement marker introduced into the sample, to measurably concentrate an analyte in a liquid (e.g., water) sample. Active, variable concentration allows otherwise lower level analytes to be concentrated in a measurable way. This enables measurements at higher (e.g., concentrated) levels, which can be extrapolated to obtain their lower, original levels based on the concentration level—measured using the introduced marker as a guide. The sample handling apparatus may be used in combination with an optic-enabled x-ray analyzer, the x-ray analyzer including an x-ray engine with an x-ray excitation path and an x-ray detection path, usable during both during the concentration and analyte measurement.
