1. What is the Cytiva Flow Rate Converter?

Definition: This calculator converts linear flow rate (cm/h) to volumetric flow rate (mL/min) for Cytiva chromatography systems.

Purpose: It helps bioprocessing professionals convert between these common flow rate units used in column chromatography.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q_{mL/min} \) — Volumetric flow rate (milliliters per minute)
• \( Q_{cm/h} \) — Linear flow rate (centimeters per hour)
• 0.01667 — Conversion factor (1/60)

Explanation: The conversion factor accounts for both the time unit conversion (hours to minutes) and the volumetric conversion based on column cross-sectional area.

3. Importance of Flow Rate Conversion

Details: Proper flow rate conversion ensures accurate method scaling between different chromatography systems and column sizes.

4. Using the Calculator

Tips: Enter the linear flow rate in cm/h. The calculator will automatically compute the equivalent volumetric flow rate in mL/min.

5. Frequently Asked Questions (FAQ)

Q1: Why convert between these units?
A: Linear flow rate (cm/h) is useful for scaling between columns, while volumetric flow rate (mL/min) is needed for pump settings.

Q2: Is the conversion factor always 0.01667?
A: Yes, this is a constant factor (1/60) that converts both the time and volume units.

Q3: Does this work for all Cytiva systems?
A: Yes, the conversion is standard for all ÄKTA and other Cytiva chromatography systems.

Q4: What about different column diameters?
A: This calculator assumes you're working with the same column diameter. For different diameters, you'll need to account for the cross-sectional area difference.

Q5: Can I convert back from mL/min to cm/h?
A: Yes, simply divide the mL/min value by 0.01667 to get cm/h.
