Capsule is a packaging method belonging to capsules, which is commonly used in medicine or health food. Capsules are generally made of medical gelatin, glycerin or other suitable pharmaceutical excipients alone or in combination. It is widely used in the pharmaceutical industry because of its functions of masking the bitter taste of drugs, protecting the properties of drugs from being destroyed, and being used to encapsulate a certain amount of drug powder.
Capsules are generally white or transparent on one side, and various bright colors such as red, orange, yellow, green, blue, purple, etc. on the other side. Such colorful colors are mainly for aesthetics and recognition. It is precisely because of the colorful colors of the capsules that it is not uncommon to have chromatic aberration problems, and the inspection of chromatic aberrations is also an important link in the quality inspection of capsule products. It is not only necessary to test the color difference between the same batch, but also to test the color difference between different batches and different workshops. Therefore, it is necessary to use a Colorimeter for detection.
Capsule color difference detection is an application of the color spectrum CS-600 Spectrophotometer . The CS600 Spectrophotometer has two calibers, and the methods for testing capsules with the two calibers of Colorimeters are described below.
1: Choose the Spectrophotometer CS-600A with general caliber. Cut the capsule to the test port for measurement, select one of the batches or samples from a workshop as the standard sample, and the rest as samples, measure the L, a, and b values, and then measure the best and worst.
2: Select the Spectrophotometer CS-600B with a caliber of 4mm. Put the capsule directly on the test port for compaction to avoid light leakage affecting the accuracy of the data, and turn on the camera to find the view, making it easier to find the measurement position. Then measure the color difference in the same way as method one.
