Abstract

Methods and apparatus for identifying an analyte in a sample are provided. The apparatus comprises an electromagnetic radiation (EMR) source in optical communication with a receptor. The receptor for receiving a sample and detecting if the sample has been presented to the receptor in a predefined manner. The receptor further directing the EMR received from the EMR source to the sample. The apparatus also comprises a detector in optical communication with the receptor, the detector for capturing transmitted, reflected, scattered EMR, or a combination thereof from the sample received from the receptor. The apparatus further comprises a user interface for presenting information obtained from the sample and the receptor, and the characteristics of one or more analytes in the sample, and a communications unit in operative association with the detector for transmitting the characteristics of one or more analytes in the sample to a processor or spectrograph.

Claims

1. An apparatus for determining the characteristics of one or more analytes in one or more sample, comprising,

an electromagnetic radiation (EMR) source;

a receptor in optical communication with the EMR source, the receptor for receiving a sample, detecting if the sample has been presented to the receptor in a predefined manner, and directing EMR received from the EMR source at the one or more sample;

a detector in optical communication with the receptor, the receptor for measuring transmitted, reflected, scattered EMR, or a combination thereof by the sample received from the receptor;

a user interface for presenting information respecting the presentation of the sample to the receptor and the characteristics of one or more analytes in the sample; and

a communications unit in operative association with the detector for transmitting the characteristics of one or more analytes in the sample to a processor.

2. The apparatus of claim 1, wherein the apparatus further comprises one or more spectrophotometers in communication with the receptor, detector and user interface, the spectrophotometer for determining one or more property of one or more analytes in the sample based on the measured reflected or scatted EMR received from the detector, directing the user interface to present information received from the receptor respecting the presentation of the sample to the receptor, and directing the user interface to present information respecting the one or more property of one or more analytes in the sample determined by the processor.

3. The apparatus as defined in claim 1, wherein the communications unit is in operative communication with a corresponding communications unit in a hand held device, a cell phone, a mobile device, or a computing device.

4. The apparatus as defined in claim 1, wherein the apparatus is housed within a hand-held device, a cell phone, a mobile device, or a computing device.

5. The apparatus of claim 3, wherein the hand held device, cell phone, mobile device, or computing device, comprises a processor, the processor comprising application software for determining one or more property of the analyte, and a user interface,

6. The apparatus of claim 1, wherein the receptor comprises a glide path or channel for directing the sample into proper orientation with the receptor.

7. The apparatus of claim 1, wherein the receptor further comprises a warning system to notify a user whether a finger, a body part, or a sample holder has not properly covered over the aperture of the receptor.

8. The apparatus of claim 2, wherein the one or more property of the analyte is transmitted to a second computing device wirelessly.

9. The apparatus of claim 2, wherein the one or more property of the analyte is transmitted to a second computing device over the internet

10. The apparatus of claim 2 wherein the apparatus comprises one or more fibre optics connectors in optical communication with the EMR, each of the one or more fibre optics providing one or more different wavelengths of EMR to one or more ports within the receptor, the receptor further comprising one or more outlet ports coupled to one or more output fibre optics each in optical communication with one or more spectrometers.
