Output Capacitance:
The data sheet advises to add 10uF capacitor to inprove load response.

Can I use also Ceramic capacitors without stability issues?

 

Basically, having a large capacitor at the output, limits the rise time,
prevents overshoots, and increases stability.

Ceramic capacitors don't have good stability properties, but for a CO2 monitor,
for a human , I guess the temperature range is low, possibly, 10 degrees to 35
degrees, so they might be OK.

Make sure you use a good quality Ceramic, NPO or better.
Polstyrene may be better, if not too large for your circuit.
