Get a list of Instrument objects. Instruments have a 1:1 mapping with Observations.

### Available end points:

- `/instruments/` - Will list all Instruments in the database
- `/instruments.json` - Will return all Instruments in json format
- `/instruments/<object_id>/` - Returns Instruments object with that id

### Available Methods:

- `GET`
- `HEAD`

### Available filters:

- `title`
- `uuid`
- `keywords`
- `instrumentType`

### How to use filters:

- `/instruments/?title__startwith!=Instrument.title: DETAILS NEEDED`
- `/instruments/?uuid=c7fa005e2095425392b18adbd7b40617`
- `/instruments.json?instrumentType=radiometer`

    "title": "Leeds: Fluorecence Assay by Gas Expansion instrument (FAGE)",
    "abstract": "This is a ground-based laser-induced fluorescence instrument for detection of OH, HO2, and RO2 radicals. OH reactivity measurements using a laser flash-photolysis technique can be provided alongside the radical measurements. The instrument is housed in and operated from a custom-built 20 ft shipping container. OH and HO2 measurement is challenging but necessary due to their role in atmospheric chemistry. The laser induced fluorescence at low pressure is measured. \r\n \r\nThis instrument has a wide range of applications including simultaneous detection of OH, HO2, RO2 radical species and total OH reactivity. Detection of iodine monoxide and glyoxal is also possible, although not at the same time as the other radical measurements.",
