Category ： Solution1
Release time： 2014-03-11 16:33
Chromium over-standard hollow capsules" have been exposed by the media, causing social attention. Depu Instruments has long been committed to the research of detection methods in the field of environmental protection health and food safety, and has carried out extensive and in-depth research on "chromium poison capsule detection" at the first time. At present, a solution has been formed.
Media exposure of poison capsules attracts attention
In the past few days, CCTV's "Weekly Quality Report" has exposed that 9 products of 13 domestic pharmaceutical companies have used hollow capsules with excessive chromium, causing an uproar in China. "Poison capsules" have become the focus of social attention.
It is reported that some pharmaceutical capsule manufacturers use industrial gelatin as the raw material for pharmaceutical capsules, while industrial gelatin is obtained from leather scraps. When leather is tanned in industrial processing, it often leads to chromium residue, and this tanned chrome-containing leather scrap is commonly known as "blue alum". Industrial gelatin processed with "blue alum skin" often has excessive chromium content.
Chromium is a toxic heavy metal, which is divided into trivalent chromium and hexavalent chromium according to different valence states. If you consume a large amount of trivalent chromium for a long time, it is easy to get diabetes, hypertension and other diseases, and it is easy to cause tumors. The toxins of hexavalent chromium are stronger, which can damage the skin and respiratory digestive system, leading to dermatitis, pharyngitis, tracheitis, gastrointestinal diseases, etc., and severe can lead to kidney failure and even cancer.
"Chromium toxin" capsules eventually flowed into pharmaceutical companies and were made into norfloxacin, amoxicilline and other commonly used drugs for sale to patients. The harm is self-evident.
Pharmaceutical capsules must be tested for heavy metals
It is reported that the 2010 edition of the Chinese Pharmacopoeia has clear provisions for gelatin hollow capsules: the raw material gelatin used in the production of pharmaceutical capsules should at least meet the standard of edible gelatin, and the content of heavy metals such as chromium, lead, arsenic, manganese, cadmium and so on must be detected before leaving the factory.
According to QB/T 4087-2010 "edible gelatin" industry standard, edible gelatin should use animal skin, bone, etc. as raw materials, and it is strictly forbidden to use any industrial waste after tanning in tanning. The national standard GB6783-94 "Food Additives - Gelatin" also clearly stipulates the content of edible gelatin: edible gelatin is divided into three categories: A, B, and C, Class A is the international advanced level, and the limit for chromium is Class A 1mg/kg; Class B is the international general level, Class C is a qualified product, and the limit of chromium is 2mg/kg.
Among the 13 kinds of chromium ultra-standard hollow capsule products exposed this time, the chromium content was as high as 181.54mg/kg, which exceeded the national standard limit by more than 90 times.
Analytical instruments make the poison capsules nowhere to hide
In response to the current "chromium poison capsule" incident, Depu Instruments responded quickly and expected to provide timely and effective solutions for major drug regulatory authorities and pharmaceutical companies.
Depu Instrument Application R&D Center has long been committed to the research of detection methods in the field of environmental protection health and food safety, and selected three capsule samples on the market for testing at the first time of the "poison capsule" incident, and formed a complete solution.
The DX-320L X-ray fluorescence spectrometer enables rapid detection of chromium content in pharmaceutical capsules. Its elemental analysis range is from sulfur (S) to uranium (U), and the detection limit can reach 1ppm, which is non-destructive, fast and easy to operate.

FAQ
Can ROHS testing instruments test metal elements?
ROHS detection instrument is a professional equipment used to detect whether electronic components, household appliances, toys and other products contain harmful substances. These harmful substances may pose a long-term threat to humans and the environment, so the application of ROHS detection instruments is of great significance.
The answer to the question of whether ROHS detection instruments can test metal elements is affirmative. Because the scope of ROHS testing not only includes harmful substances, but also includes the detection of metal element components in qualified products. These metal elements include lead, cadmium, mercury, etc., which are widely used in product manufacturing. Although these elements are necessary, excessive use poses great harm to human health and environmental protection. Therefore, the emergence of ROHS detection instruments has brought great convenience to our detection of metal elements.
Which is the best gas chromatograph?
Gas chromatograph is a commonly used analytical instrument, which is widely used in chemistry, biology, medicine and other fields. However, there are many gas chromatograph brands on the market, and the prices are far from the same, making it difficult to choose. So, which gas chromatograph is better?
First of all, we need to understand the basic principles and performance indicators of gas chromatographs. Gas chromatograph uses samples to evaporate into a gaseous state at high temperatures, separate them by column, and then detect the degree and content of different components by detectors. Common performance metrics include resolution, sensitivity, linear range, repeatability, and more.
When choosing a gas chromatograph brand, we can consider the following aspects:
1. Brand awareness and word of mouth. Well-known brands usually have high technical strength and after-sales service guarantee, and have a better reputation.
2. Technological innovation and R&D capabilities. Gas chromatograph technology is constantly updated, and brands with strong R&D capabilities and technological innovation capabilities are more competitive.
3. Product performance and price. The performance and price of different brands of gas chromatographs vary greatly, and you need to choose according to your actual needs and budget.
4. After-sales service and technical support. Various problems may occur during the use of the gas chromatograph, and after-sales service and technical support can solve the problem in time to ensure that the instrument is running.
Which is the best service provider for RoHS spectrometers?
RoHS spectrometer is an instrument used to detect harmful substances in products. It can detect whether products contain lead, mercury, cadmium, Hexavalent chromium and other harmful substances to ensure human health and environmental safety. So, which one is the best service provider for RoHS spectrometers?
Firstly, we need to understand the basic principles and detection methods of RoHS spectrometers. RoHS spectrometer is an instrument based on the principle of spectral analysis, which can determine whether a sample contains harmful substances by analyzing the elements and compounds in the sample. The detection method of RoHS spectrometer is generally X-ray fluorescence spectroscopy (XRF).
What instruments are used to detect RoHS in electronic and electrical products?
RoHS (Restriction of the Use of Certain Hazardous Substances Directive) is a regulation established by the European Union aimed at limiting the content of harmful substances used in electronic and electrical products. These harmful substances include lead, mercury, cadmium, Hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers. To ensure product compliance with RoHS regulations, specific instruments need to be used for testing.
