1. Bags of 50g each of Silica Gel and E-sorb MD were used in the test.

2. Test in Climate Chamber

One bag each of Silica Gel and TE-sorb MD were placed in a climate chamber
    and weighed once each 24th

The temperature and the relative humidity were measured from time to time
    and were found to be within

For the first part of the test the Relative Humidity was maintained at 80%.

After 9 days, when both the samples had saturated the
    Relative Humidity was increased to 95%.

The bag of Silica Gel was inadvertedly destroyed in an
    attempt to dry it after 9 days.

3. Test under Realistic Temperature Cycle

A metal container was placed outside.

Outside temperature varied between 0 and 15ï‚°C.

The Temperature and Relative Humidity was logged with a data logger.

Inside the container daily cycles occurred of:

One bag each of Silica Gel and E-sorb MD were placed inside and
    weighed once every 12 hours.

4. Result in Brief

Under RH = 80% and T = 20ï‚°C
            Silica Gel absorbs 20% of its weight

    E-sorb MD absorbs 40% of its weight

Under RH = 95% and T = 20ï‚°C

            E-sorb MD absorbs more than
    50% of its weight

Under temperature cycling conditions
            Silica Gel absorbs about    22%
            E-sorb MD absorbs about 35%

The Silica Gel show a clear "saw tooth" pattern of
    absorption/re-evaporation over the temperature cycle.

The E-sorb MD does not show such a pattern.
