Community COZI Laboratory

Community COZI Laboratory

 

As of April 2026, this Lab can no longer be accessed through applications to AMOF. However, it remains available to the community through the University of York. Contact Dr Katie Read for more details.

 

The COZI Laboratory is situated in the Wolfson Atmospheric Chemistry Laboratory (WACL) at the University of York.

Our aim is to ensure excellent national and international traceability for the measurements of ozone, carbon monoxide, and nitrogen oxides. We invite users to run, test and calibrate their new and old atmospheric instruments in our comprehensive setup.

The laboratory houses instruments that are internationally recognised and calibrated to international scales, meeting Global Atmospheric Watch (GAW) data quality objectives.

Features of the COZI Laboratory include:

  • Permanent sampling manifold with access points for instruments to run alongside the core set-up
  • Teflon chamber for chamber experiments of trace gases
  • Thermo Environmental 49C UV photometric Ozone analyser (fast response, low detection limits)
  • Aero-laser GmbH AL5001 VUV Carbon monoxide analyser (low detection limit, high resolution, fast response)
  • A NIST referenced Thermo Scientific 49i-PS Ozone calibrator
  • A 2b NIST referenced ozone calibrator
  • 2B Technologies Model 714 NO2/NO/O3 calibrator
  • NIST Carbon monoxide calibration standard
  • Working CO calibration standards referenced to NOAA over a range of concentrations and containing different matrices.
  • NPL-certified NO calibration standards (GAW standard) and working standards
  • Dew Point generator for humidity testing
  • Dry (-40degCdp) clean (scrubbed for ozone, co, nox, voc) compressed air supply
  • Pressure and laboratory temperature measurements

Infrastructure
  • The COZI Laboratory has bench and rack space for visiting instruments
  • It is a stable temperature-controlled (18C) air-conditioned environment
  • There are access points to a common sampling manifold
  • Clean (scrubbed for ozone, carbon monoxide, NOx, VOCs) and dry (-40degCdp) compressed air supply
  • Connections to Helium, N5, N6 Nitrogen, CO2 in Argon, oxygen permanent gas supplies (gas consumption will be charged for)
  • Facility for data logging using a laptop equipped with Daqfactory software
  • Meteorological data for interpreting atmospheric measurements
  • There is a Teflon chamber for chamber experiments of trace gases with controllable temperature from-2 to 40 °C, controllable humidity 35 % to 80 % RH and a volume > 1500 litres
Power
  • Single-phase 240V/50Hz power outlets are available in the COZI Laboratory
  • Three-phase power may also be available to power shipping containers that can be located outside
  • Costs will be incurred for large power usage of more than 3 kW/hr
  • Additional generators could be accommodated easily on site
  • Please contact the Instrument Scientist for more detail
Arriving
  • On arrival, please go directly to the WACL main entrance. Use the intercom system to dial the extension number for the person you are visiting (phone numbers are listed in the glass panel to your right).
  • If you have any problems please contact Jenny Hudson on 01904 322609.
Location on Campus
  • The COZI Laboratory is located across the road from the main chemistry department behind the Chemistry Hub and the Plasma Institute.
Getting to Campus
  • Parking at the university is very limited. There are several pay-and-display car parks available. If you need to park, it’s probably best to contact your host.

The instrument scientist must be made aware of all visits to the COZI Laboratory.

The user must attend an introduction to the COZI Laboratory briefing, given by instrument scientist.

The user must prepare their own risk assessment and work plan. A template is provided for this.

Emergency Provision
  • There should be at least one first aider on-site at all times.
  • A phone is always available and there is always access to a vehicle.
  • First aid supplies are available on site.

Any user owned instruments needing delivery should be shipped to the following address
