The present invention relates to a sensor cartridge (1) for inline measurement of a fluid (2), comprising: a body (10) having an interface section (11) configured to be connected to a sensor head, the interface section (11) comprising a measuring channel (12) for accommodating the fluid (2) to be measured, a pump (13) accommodated in the body (10), the pump (13) comprising an actuating member (130) being configured to be actuated by the sensor head when the interface section (11) is connected to the sensor head to pump the fluid (2) to be analyzed through the measuring channel (12), wherein the body (10) further comprises an in- and outflow section (14) connected to the interface section (11), wherein the in- and outflow section (14) comprises an inflow channel (15) and an outflow channel (16), the inflow channel (15) being in flow connection with the outflow channel (16) via the measuring channel (12) and the pump (13) so that the fluid (2) to be measured can be pumped from the inflow channel (15) via the measuring channel (12) to the outflow channel (16) to enable an inline measurement of the fluid (2).

A probe tube subassembly for a sampling apparatus, and related systems and methods are disclosed. The probe tube subassembly includes a probe tube, a retainer sleeve connected to the probe tube, an inner sleeve positioned within the retainer sleeve and comprising apertures, sample tubes, each extending within the probe tube and through a respective one of the apertures, and a sample head positioned within the inner sleeve and including a pocket located at a distal end portion thereof. The sample head is axially slidable within the inner sleeve between an extended position where the pocket is exposed to an ambient environment, and a retracted position where the pocket is covered by the inner sleeve. The disclosed subassembly and related apparatus, systems, and methods provide improved performance and ease of servicing, among other advantages.

Systems and methods for dynamically determining water quality for a water system are disclosed. A controller includes, and/or has access to, electronically stored thresholds separating zones representing states of the water system, one of the thresholds ("composite threshold") is specific to a composite water quality metric ("CWQM") and a plurality of the thresholds ("characteristic thresholds") are each specific to a respective characteristic of a sample of the water system. The controller receives data from sensors for measuring the characteristics, and determines, for each of the characteristics, a proximity of an associated measurement(s) to an associated characteristic threshold. The controller uses the determined proximities to adjust the CWQM, and determine a current state of the water system based thereon relative to the composite threshold, a representation of which is communicated to electronic device(s).

A probe head (10) suitable for Raman spectroscopy comprises an optical pathway (110) along which it is intended that light is emitted for illuminating a sample and light returns from the sample. The probe head further comprises an internal reference target selector (25) which allows to selectively bring a reference target (253) into said optical pathway, in which case the returning light, and thus the measurement signal, originate form the reference target, and to selectively provide free passage for the light to and from the sample, in which case the returning light, and thus the measurement signal, originate form the sample. The reference target has a known Raman spectrum. Measurement values from the reference target thus enable calibration of the Raman spectroscopy measurements. The internal reference target selector enables calibration without removing the probe head from a measurement setup.

An objective lens unit (6) for a microscope is disclosed. The objective lens unit is suitable to be used when at least partially submerged in a liquid sample. The objective lens unit comprises an immersion lens (64, 642) positioned adjacent a distal front end (62) of the enclosure of the objective lens unit. The immersion lens is arranged and configured to receive light through a front end optical aperture (63). An objective lens system (65, 66) is arranged inside an enclosure (61) and proximal from the immersion lens (64, 642). The objective lens system is configured to collect light received by the immersion lens (64, 642) through the front end optical aperture (63). The objective lens system comprises a motorless automated adjustable lens (65), in particular a tuneable lens, configured to amend the focal length of the objective lens system relative to the immersion lens.

Suggested is a kit of parts configured for releasably coupling and securing a tubular element (3) to a connector fitting (2). The kit of parts comprises the tubular element (3), a first clamping ring (7) configured to attach to the tubular element, a second clamping ring (8), and a latch (10) pivotably attached to the second clamping ring (8) at a pivot axis (15). A tip of the latch comprises a barbed hook (11) and is arranged with the barbed hook extending radially inward in relation to the second clamping ring and with the barb (12) extending axially towards the second clamping ring such that an undercut is shaped between an axially extending body section of the latch and the barb. The first clamping ring (7) comprises a groove (18) adapted and configured to receive the barb (12), wherein a rim shaped between the at least one groove and a radial outer circumference of the first clamping ring is sized and configured to be received within the undercut.

Systems and methods for providing artificial intelligence analysis of total organic carbon ("TOC") sensor data are provided. A TOC measurement device includes a fluid containing portion for holding a sample fluid and sensor(s) and an oxidation device at the fluid containing portion. A controller operates the oxidation device to cause the sample fluid at the fluid containing portion to experience differing levels of exposure to the oxidation device over a time period, receives measurements from the sensor(s) over the time period, each taken at a different time such that each of the measurements reflect a different exposure level of the sample fluid from the oxidation device, analyzes the measurements, including by applying a deterministic model, to determine an initial TOC measurement for the sample fluid, and applies an artificial intelligence module to the initial TOC measurement to determine an error compensated TOC measurement.

Systems and methods for generating multiple data points for total organic carbon ("TOC") analysis of an actively flowing system are disclosed. A TOC device includes a sample fluid passageway and a flow control device, conductivity sensor(s), and an oxidation device located at the sample fluid passageway. A controller operates the flow control device to cause a flow of sample fluid through the sample fluid passageway at a first non-zero flow rate while the oxidation device is active, takes measurement(s) of the sample fluid from the conductivity sensor(s), operates the flow control device to cause a further flow of the sample fluid through the sample fluid passageway at a second non-zero flow rate while the oxidation device is active, and takes further measurement(s) of the sample fluid from the conductivity sensor(s), and generates delta conductivity measurements from the measurements.
