Patent number: 10578550Abstract: A method for identifying the presence of at least one adulterant substance in a sample. The method comprises receiving sets of sample spectral data, reference spectral data, validation spectral data each set for a respective validation example, and adulterant substance spectral data for said at least one adulterant substance. From these residue data which is representative of a residue which would remain after performing a least squares fitting process between the sample spectral data and the reference spectral data is determined and modified sample residue data which is representative of a residue which would remain after performing a least squares fitting process between the sample spectral data, the reference spectral data and the adulterant substance spectral data is determined. The corresponding two residue data sets are also determined for each validation example.Type: GrantFiled: May 13, 2019Date of Patent: March 3, 2020Assignee: PERKINELMER SINGAPORE PTE LIMITEDInventors: Robert Alan Hoult, Ben Perston

Patent number: 9322703Abstract: A spectroscopic instrument comprising a compartment (2) for housing instrument components (3) and desiccant (4) to protect the instrument components, and a deformable container (5) having at least one wall portion which is movable within the compartment (2) so as to vary the volume of the compartment (2) that is occupied by the deformable container as the container is deformed. The interior of the deformable container (5) is in fluid communication with the surroundings of the instrument, such that a difference in pressure between the compartment and the surroundings tends to cause the deformable container to deform, moving the wall portion.Type: GrantFiled: August 16, 2011Date of Patent: April 26, 2016Assignee: PerkinElmer Singapore PTE Ltd.Inventors: Robert Alan Hoult, Ralph Lance Carter
