# Can a single Autoloader/iScan run contain multiple types of beadchips?

Question: Does the autoloader accept multiple chip types in the same sitting for scanning? For example, can 10 EPICs, 10 GSA, 10 Omni2.5Exomes, could all 30 chips be put together on the autoloader in one run for scanning? Or do they have to be separated into 3 different runs for scanning on the autoloader?

Answer: the autoloader allows mixed beadchip types in the same run. In fact. the scanner allows mixed beadchip types in the same carrier. Each beadchip is scanned separately, identified by barcode, and then the scanner pulls the appropriate dmap file from the dmap repository based on the barcode, uses the .sdf file contained in the dmap folder to set the parameters for the scan, and scans the beadchip. So you can run any number of different beadchip types in the same run, or even in the same carrier.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://knowledge.illumina.com/microarray/iscan/microarray-iscan-faq-list/000008643.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
