Photostability Chambers

ICH Q1B asks for a specific dose, not for a bright box: at least 1.2 million lux hours of visible light and at least 200 W·h/m² of near-UV, delivered to the sample surface. A chamber that cannot measure the dose at the sample plane cannot demonstrate compliance, whatever its lamp wattage. This family covers the two accepted routes, fluorescent D65 plus UV-A, and xenon arc.

APPLICATIONS

Photostability Chambers Applications & Use Cases

Application-led selection for real laboratory workflows.

Option 1 or option 2

The two options in ICH Q1B are different instruments, and mixing them up invalidates the study design.

The dose is the deliverable

Lux hours and W·h/m² are accumulated quantities, so the chamber has to integrate them and stop at the target.

Temperature control during irradiation

Lamps heat the chamber, and a photostability study that exceeds its temperature tolerance is not a photostability study.

What to put in the quotation

Photostability projects go wrong on accessories far more often than on the chamber.

PERFORMANCE & SELECTION

Option 1 or option 2

The two options in ICH Q1B are different instruments, and mixing them up invalidates the study design.

Option 1 uses a single xenon arc lamp with filters that approximate daylight behind window glass, D65.
Option 2 uses two light sources, a fluorescent D65 bank for visible light and a UV-A bank for 320–400 nm.
Option 2 is easier to temperature-control because fluorescent lamps add little heat to the chamber.
Option 1 gives a closer spectral match to sunlight and is preferred where the product is light-sensitive across the visible band.

CONFIGURATION & COMPATIBILITY

The dose is the deliverable

Lux hours and W·h/m² are accumulated quantities, so the chamber has to integrate them and stop at the target.

A 8,000 lux source needs about 150 hours to reach 1.2 million lux hours, which is six days of continuous running.
The UV dose accumulates separately and needs its own sensor in the 320–400 nm band.
The sensor has to sit at the sample plane, not at the chamber wall, or the reading is optimistic.
Calibration of the irradiance sensor every 500 hours is the practice that keeps the study defensible.
