Workspace analyte sensing system and method using a fan to move samples from the workspace to the sensor

A system, comprising:

• (a) a form, fill, and seal machine defining a workspace open to the atmosphere wherein packaging is filled with a product and sealed,
• (b) a flush system for flushing the workspace with an inert gas to reduce oxygen levels in the workspace,
• (c) an oxygen sensor remotely located relative to the workspace,
• (d) a tube attached to the oxygen sensor and defining a lumen through which the oxygen sensor is placed in fluid communication with the workspace, and
• (e) a fan in sealed fluid communication with the lumen of the tube for continuously moving gaseous content from the workspace into operative engagement with the oxygen sensor,
• (f) whereby the oxygen sensor can sense and report O2 levels in the workspace.

A method of controlling inert gas flushing of a form, fill, and seal machine workspace, comprising:

• (a) placing the distal end of a tube attached to an oxygen sensor within the workspace of a form, fill, and seal machine,
• (b) activating a fan in sealed fluid communication with the lumen of the tube so as to continuously move gaseous content from the workspace through the tube and into operative engagement with the oxygen sensor,
• (c) sensing and reporting O2 levels in the workspace with the oxygen sensor, and
• (d) adjusting a flow rate of inert gas into the workspace based upon the reported level of O2 in the workspace.
