Micro Plant Nitrate Nitrogen Content Assay Kit
| Cat# | PBK-021 |
| Specification | 100T/48S |
| Unit | Box |
| Description | Nitrate nitrogen is the most important nitrogen source for plants. The nitrate nitrogen content in plants reflects the supply of nitrate nitrogen in the soil and can be used as an indicator of soil nitrogen fertilization. Determination of nitrate nitrogen content in plants can not only reflect the nitrogen nutrition of plants, but also has important significance in identifying the quality of vegetables and processed products made from plants. |
| Test Method | Spectrophotometer/Microplate Reader |
| Storage Conditions | 2-8℃ |
| Shelf Life | 6 months |
| Detection Principle | Under the condition of concentrated acid, NO3- reacts with salicylic acid to produce nitrosalicylic acid, which is yellow under alkaline condition (PH>12), and its color is proportional to its content in a certain range, so the nitrate nitrogen content can be calculated by colorimetric determination. |
| Self-prepared Laboratory Supplies and Equipment | Distilled water, balance, centrifuge at room temperature, visible spectrophotometer/enzymometer, micro-quartz cuvette/96-well plate, constant temperature water bath. |
