The invention discloses a jade verification device. The jade verification device comprises a base body, an infrared light source, a detector assembly, a calcium fluoride window sheet and a control measurement assembly, wherein the base body is provided with a sample cell; the infrared light source is arranged on the base body; the detector assembly is arranged on the base body, and the infrared light source and the detector assembly are oppositely arranged at the two sides of the sample cell; the detector assembly comprises an infrared detector and a filter; the filter is arranged between the infrared detector and the sample cell; the calcium fluoride window sheet is arranged between the filter and the sample cell; the centers of the infrared detector, the filter, the calcium fluoride window sheet and the infrared light source are on the same axis; the control measurement assembly is used for controlling the infrared light source and the detector assembly. According to the jade verification device disclosed by the embodiment of the invention, not only can a sample be rapidly and accurately verified without loss, but also an optical path is not provided with any mechanical motion part. The jade verification device is compact in structure, strong in shock resistance, small in size, convenient to carry and low in cost. The invention further discloses a jade detector with the jade verification device.
Description
technical field [0001] The invention relates to the technical field of infrared spectrum qualitative analysis, in particular to a jadeite verification device and a jadeite verification instrument with the device. Background technique [0002] Jade "A" refers to natural jade without any artificial chemical treatment, and its jade quality, color, and structure are all natural. Jadeite "B goods" refers to jadeite that has been acid-leached, bleached, and wax-treated, that is, jadeite that has been soaked in strong acid and then consolidated with organic matter. This treatment uses strong acid to soak the jadeite to remove the variegated colors, and then fills the spaces in the jadeite that have been etched by acid leaching with vacuum injection. According to the national standard GB T16553-2003 (Jewelry and Jade Identification), emeralds have strong absorption peaks in the infrared spectrum at 2400-2600cm-1 and 2800-3200cm-1 (ie 3.8-4.2um and 3.1-3.6um) after bleaching and fil...
