The In Situ segment, which accounted for 72.2% of revenue share in 2022, is the largest and fastest-growing segment. It is projected to reach USD 513 million by 2028, with a compound annual growth rate (CAGR) of 6.6% during the forecast period. In-situ analyzers are specifically designed to provide accurate and rapid measurements of near-infrared absorbing gases in harsh process environments characterized by high pressure or temperature. These analyzers are capable of operating under challenging conditions involving aggressive, corrosive, and high particulate content materials. In the case of in-situ monitoring, gas analyzers are placed directly inside stacks or ducts, with a portion of the measurement device immersed in the sample gas, hence the term in-situ. These analyzers may utilize electrochemical or optical sensors, and they always provide a corresponding signal output based on the gas reading. Two types of in-situ measurements are commonly used: point (in-stack) and path (cross-stack). Point measurements are conducted at the exact location of the sampling cell, where gas analyzers are placed in a probe submerged in the flowing sample gas. Electrochemical or zirconia sensors are frequently employed in point style systems. On the other hand, path measurements involve taking measurements across the emissions stream. This is typically accomplished by sending an optical signal, such as a laser, across the stack or duct and detecting the reflected signal. Path measurements enable the selective absorption of specific pollutants and the interpretation of their concentrations within the gas sample. In-situ gas analyzers find extensive applications in various industries, including metal heat treating, paper, steel, and power sectors. For instance, an in-situ oxygen analyzer can be used to analyze flue gas streams from boilers, while carbon monoxide can be measured in dew point or heat treat furnaces within atmosphere gas generator lines.

The Tunable Diode Laser Spectroscopy (TDLS) segment, which accounted for 75.8% of revenue share in 2022, is also the largest and fastest-growing segment. It is expected to reach USD 533 million by 2028, registering a CAGR of 6.4% during the forecast period. Tunable Diode Laser Spectrometers (TDLS) operate by measuring the level of laser light absorption as it passes through the gas being analyzed. This technology facilitates real-time gas analysis, leading to increased efficiency, safety, throughput, quality, and environmental compliance. TDLS is particularly effective in measuring the concentration of specific species, such as methane and water vapor, within gaseous mixtures using tunable diode lasers and laser absorption spectrometry. The key advantage of TDLS over other techniques is its ability to achieve very low detection limits. The growing concerns about global warming have prompted economies worldwide to invest heavily in new technologies for detecting and limiting hazardous gases, including CH4, CO2, CO, H2S, and HONO in the atmosphere. Consequently, tunable diode laser analysis is in high demand across various industrial sectors. In particular, tunable diode laser absorption spectroscopy (TDLAS) has proven instrumental in reducing greenhouse gas emissions and measuring combustion gas emissions. Furthermore, supportive government policies in the region are driving the growth of tunable diode laser analyzers throughout the forecast period.

The Chemical segment, accounting for 30.8% of revenue share in 2022, is the largest and fastest-growing segment. It is projected to reach USD 222 million by 2028, with a CAGR of 6.8% during the forecast period. In the chemicals industry, oxygen is one of several undesired contaminants that can negatively impact reactions or degrade the final product. For example, olefin co-catalyst systems can produce high-quality and high-yield polyolefin products only if the olefin feedstock stream is oxygen-free. In such cases, oxygen gas analyzers play a vital role by providing low ppm capabilities to ensure optimal product conditions. Another common practice in chemical storage or transportation involves blanketing highly flammable products to reduce the risk of explosion. Laser gas analyzers are employed in blanketing operations to monitor the presence of undesired gases below the explosion risk threshold. For instance, when hydrocarbon liquids are stored in tanks, air leakage into the headspace above the liquid level can lead to the formation of explosive gas mixtures. To mitigate this risk, carbon dioxide or nitrogen is injected into the headspace above the liquid to displace any air.

Process gas analyzers play a crucial role in ensuring the safe and efficient operation of various chemical production steps. They are essential components in preventing the development of explosive conditions in reactors and controlling combustion in thermal oxidizers. Hydrogen is a key product and intermediate in the chemical industry, commonly used as a feedstock for ammonia production, among other applications. Consequently, there is significant demand for hydrogen analyzers to determine hydrogen concentration within gas mixtures. The strong growth observed in the chemicals industry in recent years is expected to drive substantial demand for gas analyzers. For example, BASF reported a 6.1% growth in global chemical industry production in 2021. The organization projected a further 3.5% growth in 2022, surpassing pre-pandemic averages.

The Asia-Pacific region, accounting for 54.8% of revenue share in 2022, is both the largest and fastest-growing segment. It is projected to reach USD 388 million by 2028, with a CAGR of 6.5% during the forecast period. Asia-Pacific is the only region to have witnessed growth in oil and gas capacity in recent years, with the addition of four new refineries contributing approximately 750,000 barrels per day to global crude oil production. Increased investment in new plants within oil and gas, steel, power, chemical, and petrochemical sectors, coupled with the adoption of international safety standards and practices, is expected to drive market growth. The development of industries in the region has heightened the demand for gas analyzers, which are employed in various applications within the oil and gas sector. Their usage spans process monitoring, safety enhancement, improved efficiency, and enhanced product quality. Consequently, refineries in the region are actively deploying gas analyzers across their plants.

The Asia-Pacific (APAC) region is characterized by the largest population demographic of older individuals. China alone has approximately 166 million citizens aged over 65, surpassing the combined elderly populations of Japan, Germany, and Italy. Additionally, gas analyzers are being utilized to analyze pollution levels within cities. Countries like China and India are experiencing alarmingly high pollution levels, leading to the deployment of gas analyzers for monitoring and controlling pollution. Researchers worldwide are working to reduce greenhouse gas emissions, utilizing gas analyzers for analysis purposes. For instance, scientists in Southeast Asia are investing in measuring Greenhouse Gas (GHG) emissions from goats and cattle, investigating the effects of different feeding regimes and implementing portable FTIR gas analyzers provided by Gasmet Technologies. These factors are expected to drive the market for gas analyzers in the region.
