Spectrum Analytic is open during COVID-19 and continuing to process samples.

We are in operation Monday - Friday 8:00 AM to 4:30 PM EDT. Please be sure to send correct paperwork when submitting samples.

Plant stage of growth is very important information to have correctly on plant tissue samples. This time of the year the stages change quickly. Corn plant samples are at upper mature (3rd) leaf until tasseling and then goes to ear leaf. Soybeans are most recently mature trifoliate. High tunnel tomatoes we need the most recently mature compound leaf. Be sure to send a double fist size of plant material.
