Negative peak troubles
I work in a food factory, our products are mainly used for export, so the quality requirements are very strict. We use a liquid chromatograph ( differential detector) to detect the content of maltose. When we check the system with water for injection, we will have a negative peak every time. This is when we have the most headache. We used a certain brand (here). A chromatographic workstation that does not name the name. I found this workstation over and over (I am familiar with some features), and finally I didn't find the function to deal with negative peaks. However, my spectrum has a lot of negative peaks. If it is not calculated, the result is not up to standard. The figure is generally this (see Figure 1) Later, I searched the Internet a bit. The netizen said that the SEPU3000 chromatographic workstation handled the negative peaks very well. I gave advice to our manager, and later bought a set, which has a function to deal with negative peaks (see figure ) Organic Turmeric Extract is derived from the dried rhizomes of turmeric. Turmeric is a ginger plant with a botanical name of Curcuma longa L. The main ingredients of Turmeric Extract are curcumin. And the curcumin ratio can reach 95% or more. Turmeric has long been used as a natural pigment (E100) in the food industry. It has strong tinting strength, does not fade, but is sensitive to light, heat. Mainly used for dyeing canned foods, sausage products, and sauces.
