To get started with a sampling regime for 1,4-dimethylnaphthalene (DMN), also known as 1,4SIGHT, you’ll first need a sampling kit from DiChlor (we’ll send one to you free of charge). The kit contains a coring tool, gloves, alcohol wipes, sample bottles, and instructions for sampling. An instructive video is available upon request. Please contact the laboratory to receive your sampling kit and/or sample bottles.
If you’re unable to sample for DMN in this manner, we also accept samples in the form of four tubers placed in a sealed paint can shipped to the lab. When samples are received this way we do the coring and extraction at the laboratory. The most accurate results will be obtained when cans are filled with tubers as much as possible to reduce headspace. Please note that the only way to get an accurate analysis of your tubers is if they are either cored immediately after sampling or sent in a sealed paint can.
