土壤、淤泥和沉淀物等

Biochemical Methane Potential is an anaerobic analysis that consist in small scale reproduction under optimal conditions of the anaerobic digestion of the complex organic molecule in order to have simpler molecules, with the final production of biogas. Find out how to determine the BMP of sludges from the municipal sewage plant.
 

了解如何测定土壤样本中的碳、氢、氮和硫。

碳氮比非常重要，因为它直接影响残留物的分解和土壤中的氮循环。VELP CN 802 的性能是通过参加 WEPAL（瓦赫宁根分析实验室评估计划）组织的能力测试计划进行评估的。

污水处理厂产生的污泥具有改善土壤性质和提供植物生长所必需的重要养分和微量元素，因此正受到越来越多的关注。总有机碳含量的测定非常重要，因为土壤中过高的总有机碳含量会阻碍厌氧消化过程，限制底土氮富集。

Learn about RESPIROMETRIC Sensor System for Soil Analysis; VELP's laboratory equipment designed to measure the soil respiration in order to:
- determine the soil microbial activity;
- establish the effect of additives (nutrients, pollutants, soil improvers, etc.) on the metabolic performance of microorganisms;
- determine the microbial biomass.

Learn how to obtain the optimal rate of plastic material biodegradation in test soil by controlling soil moisture, as well as, determining the ultimate biodegradability of the material itself. A non-specific soil is used as the inoculum because the test simulates the processes of biodegradation that occurs in a natural environment.

消化阶段是凯氏定氮分析中最耗时的步骤。加快消化过程并确保正确的结果对提高实验室效率至关重要。
VELP设计了七种不同类型的KjTabs™片剂来加速矿化过程。除了催化剂，VELP 还生产消泡 KjTabs™，以减少矿化过程初始阶段泡沫的形成。

在不同的非生物基质（污泥、土壤、沉积物）和生物基质中对PCBs进行监测，并对二恶英类同源物进行限制。下载应用说明，了解 SER 158 在沉积物样品中PCBs方面的应用。

了解如何确定溶胶中的氮。 植物中的氮是许多化合物的一部分，包括蛋白质，酶，核酸，叶绿素和所有生物功能所必需的维生素。
