It is also used for buffering solutions to make them slightly alkaline during chemical purification, such as high-performance liquid chromatography.
Because it entirely decomposes to volatile compounds, this allows rapid recovery of the compound of interest by freeze-drying.
Relatedly it is also useful as an alkaline buffering agent for analytical LC–MS as its volatility allows it to be rapidly removed automatically from the sample stream in the low pressure spray chambers used by many standard mass spectrometry detectors found at the end of typical LC-MS systems, such as electrospray ionization detectors.
This is critical as most mass spectrometry detectors become signal saturated or even damaged with more than a trace amount of ions entering the detector proper at any one time.
This issue limits buffering agents and other additives in LC-MS buffers to either extremely trace concentrations or to fairly volatile compounds.
In pH ranges from about 7 to 9, ammonium bicarbonate is one of the only options available as the primary buffering agent for most LC-MS buffers.

Safety Profile Of E 503 Ammonium bicarbonate:
E 503 Ammonium bicarbonate can release ammonia gas (NH₃) and carbon dioxide (CO₂) upon decomposition, particularly when heated.
Inhalation of ammonia fumes can cause irritation to the respiratory tract, leading to coughing, throat discomfort, shortness of breath, and, in sensitive individuals, exacerbation of asthma or other chronic respiratory conditions.
In industrial or food-processing settings where large quantities are handled, proper ventilation and respiratory protection are recommended to prevent inhalation hazards.
Direct contact with E 503 Ammonium bicarbonate in its solid form or in concentrated solutions may cause mild to moderate irritation to the skin, producing redness or itching in sensitive individuals.
Eye contact with dust or dissolved material can lead to burning, watering, or redness, so it is important to wear protective gloves and safety goggles when handling the chemical in industrial or laboratory environments.
While E 503 is generally recognized as safe in the quantities used for food applications, accidental ingestion of large amounts of ammonium bicarbonate could result in gastrointestinal discomfort, including nausea, vomiting, or abdominal pain.
This is due to its alkaline and ammonia-releasing properties, which can irritate the stomach and intestines if consumed in excessive doses.
