Is it forbidden to buy pesticide standards? Pesticide label
Excuse me, when making pesticide residues, are the pesticide residues standards you purchased solid or liquid, and what are the advantages and disadvantages of each?pesticide standardHow long is the shelf life?
Answer: Generally, if you buy liquid, you don't need to weigh it.
answerFor agricultural residue projects, if there is a national standard, try to buy the national standard (the national standard liquid is cheaper). If there is no national standard, you can only buy the external standard.
answerFor solid and liquid labels, it mainly depends on your dosage, because liquid labels are generally 100ppm * 1ml.pesticide standardThe shelf life is generally one year.
answerLiquid labels are generally one-third to one-half the price of solid labels, that is, the money to buy 2 identical liquid labels is basically almost enough to buy a solid label. If the dosage is relatively large, it is more cost-effective to buy a solid label. And some pesticide standards do not have liquid labels, only solid labels.
