An analytical rotor system comprises a rotor and interface. The rotor defines a plurality of chambers configured to process a sample to perform a Method of Standard Additions (MSA) test in response to centrifugal force. The rotor also defines a plurality of capillaries configured to transfer the sample between the chambers in response to the centrifugal force. The interface is configured to couple to the rotor and to an analytical device that spins the rotor to provide the centrifugal force. A first one of the chambers comprises a sample-only chamber that includes a first portion of the sample in response to the centrifugal force but does not include a standard. A second one of the chambers comprises a first standard addition chamber that includes a first portion of the standard that is added to a second portion of the sample in response to the centrifugal force.

A differential pH probe design uses a container having an outer surface and an inner volume, where the inner volume is divided into a first, a second, and a third chamber. A first pH-sensitive area is located on the outer surface of the first chamber where the first pH-sensitive area is configured to be exposed to a sample. A second pH-sensitive area is located on the outer surface of the second chamber where the second pH-sensitive area is shielded from the sample and is exposed to a first buffer solution. A third pH-sensitive area is located on the outer surface of the third chamber where the third pH-sensitive area is shielded from the sample and is exposed to a second buffer. A first electrode is configured to detect a first voltage across the first pH-sensitive area, a second electrode is configured to detect a second voltage across the second pH-sensitive area and a third electrode is configured to detect a third voltage across the third pH-sensitive area. Circuitry is configured to process the first voltage, the second voltage, and the third voltage to determine a pH of the sample.

The rotor also defines a plurality of capillaries configured to transfer the sample between the chambers in response to the centrifugal force. The interface is configured to couple to the rotor and to an analytical device that spins the rotor to provide the centrifugal force. The rotor includes a sample chamber configured to receive and hold the sample, and in response to the centrifugal force, to transfer the sample through a sample port to at least one of the chambers. The sample chamber is shaped so a fluid level of the sample does not reach the sample port while the sample chamber is at rest, but the fluid level of the sample does reach the sample port when the sample chamber is spinning.

An analytical rotor system comprises a rotor and interface. The rotor defines a plurality of chambers configured to process a sample to perform a titration test in response to centrifugal force. The rotor also defines a plurality of capillaries configured to transfer the sample between the chambers in response to the centrifugal force. The interface is configured to couple to the rotor and to an analytical device that spins the rotor to provide the centrifugal force. A plurality of the chambers comprise titration chambers that hold different proportions of a titration reagent and the sample in response to the centrifugal force and wherein-at least one of the titration chambers indicates an event that corresponds to one of the proportions of the sample and the titration reagent.

An analytical rotor system comprises a rotor and interface. The rotor defines a plurality of chambers configured to process a sample to perform a first test in response to centrifugal force. The rotor also defines a plurality of capillaries configured to transfer the sample between the chambers in response to the centrifugal force. The interface is configured to couple to the rotor and to an analytical device that spins the rotor to provide the centrifugal force. One of the chambers comprises a first analytical chamber that is configured to allow a first analytical signal to traverse a first analytical signal path through the first analytical chamber to perform the first test. The first analytical signal path is parallel to a plane of the spin.

A method for manufacturing a differential pH probe body by forming a plurality of tube shaped segments where each of the plurality of tube shaped segments comprises a first section formed from a pH sensitive material and a second section formed from a non-pH sensitive material. Coupling the plurality of tube shaped segments together end-to-end to form the differential pH probe body where the pH sensitive sections alternate with the non-pH sensitive sections and then closing one end of the differential pH probe body.

A carrierless method is described for the analysis of a fluid sample for determination of the presence of a chemical species in the sample or for the determination of a physical characteristic of the sample. A portion of sample is drawn into a holding coil, followed by drawing one or more reagents (if desired) into the holding coil, then moving the sample and reagent (or reagents) through the reaction coil to a detector (e. g. , calorimeter, potentiometer, ion selective electrode, fluorimetric detector, photometric detector, etc. ). No separate carrier fluid is used in this method.
