# How Much Sample Material Should I Send?

For optimal measurements, the recommended sample quantities are:

- **30-50 mg of sample material** is typically recommended.
- It's better to provide slightly more material, especially for samples that are statically charged, as this makes loading easier.

#### Requirements:

- It is possible to work with less than 30 mg, but the sample wells must be completely filled.
- For low-density samples, even 10–20 mg might be sufficient.
- The critical factor is filling the **sample holder wells**, which are approximately **2.5 mm diameter** and **1 mm thickness.**

 It's helpful to compare your available sample volume with the pictures in the [shipping instruction guide](https://help.momentum-transfer.com/how-to-ship-your-samples-to-us?hsLang=en)

- Samples should be in **powder** or **polycrystalline solid** form
- For shipping, use transparent glass or plastic containers with at least a 5 mm opening and a maximum length of 5 cm.
- Labels should be printed and partially placed so the contents remain visible.

Remember that the samples cannot be returned after measurement, so it's advisable to send only the amount required for 1–2 measurements (just in case).

**Please do not send more than 100 mg.**
