A minimum sample charge is billed for batches less than 100 samples for nutrient analysis and 30 for solid phase carbon and nitrogen. Samples that are batched or that can be delayed in data delivery can avoid minimum sample charges.  If you have a smaller sample load, samples can be stored and batched with other projects until there are 100 samples for analysis to avoid the minimum sample charge.
