Custom Purity Tests: Blend and Mixture Verification

If a sample is a blend or mixture, testing can be requested for the verification of species and the specified percentages of components. Additional testing for overall germination or the germination of each species may also be requested.

Examples of recent tests include:

• Samples of a mixture for wetlands were submitted for identification of seed species present. Component species were identified, weighed and reported.
• A buyer had purchased a blend of turf grass and wanted to verify if the sample contained the kinds and proportions listed in the label.
• Plants were sent for grow-out and identification of plants from a golf course (live plants were sent in for us to grow and identify).
• Examined seeds used in a new planting process to test for viability of seeds after processing. The seed mixture was sprayed through a hose at high speed and the customer had it checked for damage to the seeds.

Testing fees are based on hourly charges.
