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": "York: FAAM-based Gas Chromatograph - Mass Spectrometer",
    "abstract": "The York portable Thermal Desorption-Gas Chromatograph-Mass Spectrometer (GCMS) fitted on board the FAAM BAe-146 aircraft is an Agilent 6850 GC- 5975 MS with a Markes International TT24-7 thermal desorption unit.  The output includes mixing ratios of a wide range of volatile organic compounds (VOCs), including halomethanes and hydrocarbons. \r\n\r\nThe sampling frequency is approximately 5 min and every valid sample will be part of the dataset; no averaging done.\r\n\r\nAir samples are drawn from the main sampling manifold of the aircraft via a metal bellows pump. The instrument comprises a water removal system through which the air sample stream passes before entering the thermal desorption unit that is coupled to the GC-MS.\r\nThe Mass Spectrometer can be run in scan or selected ion monitoring mode depending on the focus of the campaign and species and on required sensitivity. \r\n\r\nThe instrument is calibrated regularly using a mixed gas standard that varies depending on the requirements of the campaign\r\n\r\n",
