About Us


Founded in Cork City in 2000 by Brian Quaid, Q Instrument Services has grown into one of Ireland’s leading specialists in gas detection and gas analysis solutions. From the beginning, our focus has been on providing reliable equipment, expert technical support, and a high standard of service to help businesses operate safely and efficiently. Over the years, we have built a strong reputation for quality, knowledge, and trust within the industries we serve.

In 2019, Seán joined the business, strengthening Q Instrument Services as a true family-run company. Combining experience, technical expertise, and a commitment to continuous improvement, we continue to grow year on year while maintaining the personal service and attention to detail that our customers value. We take great pride in developing long-term relationships with our clients and supporting them with solutions tailored to their individual requirements.

Today, Q Instrument Services is proud to work with some of Ireland’s largest and most respected organisations, including Pfizer, Eli Lilly, Pepsi, Viatris, and Johnson & Johnson, alongside many valued local businesses and contractors. Our mission remains the same as it was when we started — to provide dependable gas detection and gas analysis solutions, backed by expert knowledge and a genuine commitment to customer safety and satisfaction.
