Formaldehyde is a key parameter in water quality monitoring and industrial waste gas analysis. Traditional reagents require manual preparation—a tedious process—and have a short shelf life (only one month). To address these common industry challenges, Lianhua Technology has launched two rapid formaldehyde detection reagents: LH-JQ and LH-JQ-F11. Both utilize mainstream spectrophotometric methods compliant with national standards, allowing for flexible selection based on the specific testing scenario.
1. Ready-to-use kits: No learning curve
Both rapid detection reagents feature a standardized kit design, eliminating the need for manual preparation. Users can complete the entire testing process simply by following the instructions, making it easy even for beginners to get started. The products are compatible with standard laboratory spectrophotometers and suitable for various applications, including routine testing and on-site sampling, offering excellent versatility.
2. Tailored solutions: Choose the right fit for your needs
① LH-JQ Formaldehyde Detection Reagent
Uses the acetylacetone spectrophotometric method, complying with national standards HJ 601-2011 and GB/T 15516-1995. It is suitable for surface water, groundwater, industrial wastewater, and industrial waste gas analysis. The reagent offers strong resistance to interference—minimizing the impact of phenols and common aldehydes—and features an extended shelf life (over 3 months) for maximum flexibility.
② LH-JQ-F11 Formaldehyde Detection Reagent
Uses the AHMT spectrophotometric method, which is the designated arbitration method for indoor air formaldehyde testing under the GB/T 16129-1995 standard; it is also suitable for detecting formaldehyde in industrial wastewater. National standards confirm that this method offers strong resistance to interference from substances such as acetaldehyde, acrolein, sulfur dioxide, and nitrogen dioxide. It is minimally affected by environmental conditions and offers high sensitivity for low-level detection, with a minimum detection limit of 0.01 mg/L. 3. Proven, stable formulations offering excellent long-term cost-effectiveness
Both reagents utilize proven formulations, eliminating errors associated with manual reagent preparation at the source. They deliver accurate, reliable results that meet the acceptance criteria for various projects. Designed for on-demand use to minimize waste, they offer a low cost per test; selecting the right product for your specific application can further reduce overall consumable expenses.
