Fluid analyser systems
Fluid analyzer systems are provided which can detect a multitude of fluids in a sample to a very high level of accuracy which includes the detection of the presence of very small amounts of fluids. The results are both qualitative and quantitative. The systems consist of a receptacle which is filled with the fluid sample to be analysed which is placed into a consistent light condition environment where its temperature is measured. Under a predetermined time duration, Charge-Coupled Device (CCD) detector(s) receive by absorbance, radiation from the fluid sample at known wavelengths and are matched against a databank of known wavelengths of fluids. Matching wavelengths within a pre-defined tolerance will determine whether an individual fluid is present or not.
1. A fluid analyser system for measuring radiation emitted by a fluid sample comprising:
a sealed receptacle, comprising a deflated flexible sample bag closed by a top, the top having mounted thereon a non-return valve and a conduit through which the fluid sample is supplied to the interior of the bag being inflated on receiving the fluid sample via the conduit, the receptacle thereby containing only the fluid sample;
a consistent light condition chamber in which the receptacle is placed;
at least one detector that detects the radiation emitted by the fluid sample, said at least one detector being located at a predetermined distance from the fluid sample; and
means for receiving and amplifying the signal from the at least one detector and enabling identification of the intensities and the wavelengths at which the radiation emitted by the fluid sample has peak intensity, where by the fluid sample is non-invasively analysed.
2. A fluid analyzer system according to claim 1 further comprising a temperature sensor for determining the temperature of the fluid sample.
3. A fluid analyser system according to claim 1 also containing a light meter for determining the consistent light condition environment.
4. A fluid analyser system according to claim 1 , containing means whereby the peak intensities and peak intensity values are summed and/or correlated with known/unknown peak intensities and/or peak intensity values (nm wavelength values) to indicate the nature of the fluids present in the fluid sample and to determine the concentrations of the fluids in the fluid sample.
5. A fluid analyser system according to claim 1 operated via a computer driven software system which provides an advisory status report of the content of the fluid and the conditions under which the test was performed.
6. A fluid analyser system according to claim 1 in which the walls of the receptacle have a high optical clarity and are flexible but not elastic.
7. A fluid analyser system according to claim 1 , in which the shape of the inflated receptacle is such that it is a firm fit within the consistent light condition chamber.
8. A fluid analyser system according to claim 1 , wherein said chamber contains a mechanism that permits a temperature probe to be inserted through a wall of the chamber to touch a surface of the receptacle whereby the probe measures a temperature of said fluid sample without penetrating the surface of the receptacle.
9. An analyser system according to claim 1 that operates and transmits/receives test data remotely.
10. A fluid analyser system according to claim 1 , further comprising a database of known fluids and wavelengths of radiation they emit for comparison with the wavelengths of the detected radiation of the fluid sample.
11. An analyser system according to claim 1 in which the consistent light environment chamber is made of a single material.
12. An analyser system according to claim 11 in which the chamber is formed from a medical grade polypropylene.
13. An analyser system according to claim 1 , wherein said at least one detector is a radiation absorbance device.
14. An analyzer system according to claim 1 , wherein the flexible sample gas has a base at an end opposite from the top and is inflatable to collect the sample by pulling the base away from the top.
15. An analyzer system according to claim 1 , wherein the flexible sample bag has a non-return valve at each end whereby the fluid sample can pass through the inflated receptacle.
