| 24 | Method and apparatus to characterize pressurized liquid sample | US15407157 | 2017-01-16 | US20180202967A1 | 2018-07-19 | Hung-Te Hsieh |
| A method for measuring the physical properties of a drug formulation suspended in a pressurized liquid propellant and a system to enable such measurements is disclosed. Drug formulations suspended in pressurized liquid propellant used in Pressurized Metered Dose Inhalers (pMDIs) are propelled in their native liquid state into an analytical instrument with a measurement cell capable of withstanding the pressure required to retain the sample in liquid form by employing a device to rapidly release the contents of the pMDI canister into the measurement instrument wherein the sample's electrophoretic mobility and size may be determined by MP-PALS or other techniques. A series of valves permits the maintenance of the high pressure in the system. Once the measurements are made, the pressurized liquid is allowed to pass to waste or another analytical instrument by opening an exit valve. | ||||||

| Apparatus for determining particle-size distribution of a sample by light-scattering includes a helium neon laser (102), a sample cell having cell windows (120, 122) and a focal plane detector (124). Detectors are also provided for detecting light scattered by a sample within or flowing through the sample cell. The apparatus includes a first (114) and second (116) folding mirrors arranged to fold the optical path from the laser to the sample cell so that the laser is vertically below the sample cell. The folding mirrors are mounted within a dust-proof housing (104), the entrance (106) and exit (108) components thereof being other optical components generally used within light- scattering apparatus. The entrance component is mounted such that its outward normal points downwards and the exit component is mounted substantially vertically so that these components do not accumulate dust. The invention allows the laser of a light-scattering apparatus to be positioned vertically below a sample cell of the apparatus without the accumulation of dust on optical components, which tends to degrade performance. | ||||||

| A photometric device for investigating a sample, comprises an array of radiation sources that are spaced apart from one another, and which are operable to generate radiation that differs from that generated by the other radiation sources in the array. The device includes a lens arrangement for focusing the radiation at a region of space where a sample may be located for example by means of a sample holder, and at least one detector for receiving radiation from the region of space. Preferably, a number of detectors are employed that are spaced apart from one another, and especially about an axis of the device, so that one radiation detector can detect radiation transmitted by the sample and the other detectors can detect radiation scattered by it. The radiation sources may be time division multiplexed so that in each time slot the detectors receive radiation originating from each radiation source. In an alternative embodiment, the radiation from the region of space may be transmitted to the sample via a beam homogeniser, for example an optical waveguide in the form of an optical fibre, which may be used to reduce or remove speckle where laser diodes are employed as the radiation sources. The device may be used to determine the particle size distribution of particles in a sample by a method employing Bayesian inference. | ||||||
