# Are There Restrictions On Samples?

The measurements offered are **only** suitable for **powdered samples**, not single crystals. We can also work with **polycystalline solids** such as **plastics** or **alloys, semi-solids** such as **gels, creams, pastes**, etc, and have even measured films deposited on substrates. Our current sample holders are not fully sealed against oxygen or moisture, so we advise against sending samples that are highly sensitive to air or humidity. We are working on improvements to accommodate these needs. We are **unable to handle liquids, gases, biological samples (e.g., animal tissues), or any dangerous materials**: including samples that are poisonous, biological, radioactive, explosive, carcinogenic, mutagenic, reprotoxic (CMR), highly reactive, unstable, or pose other significant hazards.
