Low-pressure liquid chromatography (LPLC) is an analytical technique widely employed for separating and purifying biomolecules, pharmaceuticals, and chemical compounds. It operates under lower pressure than high-performance liquid chromatography (HPLC), making it suitable for tasks where high-resolution separation is less critical and cost efficiency is prioritized. Due to its simpler operation and minimal requirement for sophisticated equipment, LPLC has found applications across research labs, pharmaceutical industries, and biochemical processing. LPLC systems typically leverage gravity flow or low-pressure pumps, providing a controlled environment for sample separation without compromising the integrity of delicate compounds, which is particularly valuable in protein purification and extraction processes.

The Low-Pressure Liquid Chromatography Market Size was valued at USD 7.25 billion in 2023 and is expected to reach USD 13.72 billion by 2032 and grow at a CAGR of 7.36% over the forecast period 2024-2032.
