The detailed investigation of soil pollution in agricultural land in the country has entered a critical period. The Ministry of Ecology and Environment, the Ministry of Natural Resources, and the Ministry of Agriculture and Rural Agriculture have jointly organized a detailed training promotion and quality management demonstration training class to ensure that the soil pollution of agricultural land is completed at the end of this year. Task. This detailed survey of soil pollution has set up a total of 553,000 farmland sites, which is more than 10 times the number of soil pollution investigation missions conducted from April 2005 to December 2013. The time is very tight and the task is very heavy. .
Soil matrix varies across the country, and the composition varies greatly. Quality control samples are mostly ppm-level, but there are also ppb levels. As a microwave digestion expert, the most important method is the method, we understand the Chinese soil better.屹尧, means choosing more targeted solutions.
Microwave Digestion, Microwave Digestion Analyzer, Soil, Technology, High-Throughput
Reaction tank cleaning problems?
The poor digestion method will cause the digestion tank to digest the soil sample and form black carbon deposit, which will affect the next digestion.
TOPEX finds more reasonable acid ratios through thousands of samples, and upgrades and optimizes digestion procedures once and for all.
TOPEX digestion tank not only has excellent performance, but also easier assembly. 40 tanks, one person, 30 minutes to complete the assembly!
TOPEX+: Microwave extraction, we are also experts!
The Ministry of Ecology and Environment recently released the “Soil and Sediment, Extraction of Organics—Microwave Extraction Method” (Draft for Soliciting Opinions) in April. Microwave extraction is about to officially become the new standard in this area. TOPEX+ powerful microwave extraction function will be for you Soil detection work provides more intimate help! Kill two birds with one stone and buy it to earn it.
More efficient: Complete parallel extraction of 40 samples in 30 minutes
More convenient: It only takes 2 steps to complete the assembly of 100mL extraction tank
Safer: Solvent sensor for monitoring solvent leaks and start defenses in a timely manner
Higher recovery: High-efficiency magnetic stirring.
TOPEX+, more assured choice
屹尧Microwave digestion instrument, with excellent quality and excellent cost performance, has been widely used in hundreds of provincial-level and above related environmental protection, food and medicine, disease control, immigration and other related laboratories. In 2018, 屹尧TOPEX series microwave The digester has been upgraded to TOPEX+, increased power mode, ramp temperature increase mode, pressure limit and boost rate monitoring mode, added power correction, infrared temperature correction, temperature and pressure limits, etc. The true resolution is more thorough and safer to run. The hardware is more secure and the software is more at ease.
Edit Comment
The content of heavy metals in crops and Chinese herbal medicines has received more and more attention. The problem of soil heavy metal pollution has surfaced. It is reported that the Ministry of Land and Resources is drawing maps of soil heavy metals pollution in China. It can be seen that the problem of excessive heavy metals in soil has been strongly challenged by the state and the government. Concern. Microwave digestion has the advantages of fast heating, uniform heating, and time-saving environmental protection. It has been favored by analysts and has been increasingly applied to sample preparation.
