32 µL Quartz Flow Cell: Aligning a Small Sample Region (MQQFC095)
Custom design guide · MQQFC095
MQQFC095 combines a nominal 10 mm path and 32 µL capacity with two top connection tubes. The measurement centre is 8.5 mm above the cell base. Choosing this cell means matching a small sample region to the beam, as well as fitting the body into the holder.
The situations and proposed changes below are planning examples, not completed customer projects.

Bring the sample through tubing
A flow cell is worth considering when the method needs liquid delivered through tubing while the cell stays in the holder. MQQFC095 combines that arrangement with a nominal 10 mm path and a small measurement region near the base. Selection therefore starts with the beam position, followed by the route and support of the two top connections.
Plan the complete sample route before treating the 32 µL capacity as a sample budget. The supply tubing, connectors and flushing procedure also hold or consume liquid. A small cell can still need a much larger amount for one complete exchange.

Start with the beam height and size
The source drawing gives an 8.5 mm measurement-centre height and a separate 2 mm optical-area hole. Compare these with the instrument beam and the actual support surface. The hole dimension is a source feature, rather than a verified usable aperture for your setup.
Mechanical fit is only the first check: a holder may accept the 12.5 × 12.5 mm footprint while leaving the beam partly outside the sample region. Show the beam centre, width and height on a holder drawing or labelled photograph. This distinguishes a body-fit request from a request to move the measurement region.
Leave room to connect both top tubes
The body is 35 mm high and the fixed height including tubes is 45 mm. Add the space for fitted hoses, connectors and removal. Support the tubing so its weight or movement is not taken by the quartz tubes. Specify the liquid, flow and pressure separately; the 3 mm OD / 1 mm ID connections do not provide an operating rating.

Keep the path and change the centre height
If the 10 mm path suits the method but the beam sits at another height, mark the required centre from the surface that actually supports the cell. Include beam dimensions and the compartment outline.
State whether the 12.5 × 12.5 mm holder interface and top connection positions must remain fixed. We can then assess a new measurement centre alongside the cavity and windows. A spacer changes the position of the whole cell, including the tubes; it should not be assumed to solve an optical mismatch within the available overhead space.
Checks to agree before ordering
- Beam fit: Check height, size and obstruction against the holder and sample region.
- Sample exchange: Observe filling, bubbles and flushing with the proposed complete circuit.
- Connections: Agree tube mating dimensions, support and operating conditions before ordering.
Sample and cleaning conditions
Check sample and cleaning liquids against the complete cell, including its bonded seams and any wetted cap or connection. Supply chemical identity, concentration, temperature and contact time. Avoid hydrofluoric acid; strong alkalis, heat and prolonged soaking need specific review. Adhesive-bonded quartz does not provide blanket approval or rejection of organic solvents.
