Screening of Ethylene Glycol (EG) and Diethylene Glycol (DEG) in Medicinal Syrup
In the pharmaceutical landscape, ensuring the safety and quality of medicinal syrups is paramount. One of the key concerns in this regard is the potential presence of harmful substances such as Ethylene Glycol (EG) and Diethylene Glycol (DEG). This article delves into the critical role of advanced analytical instruments, such as Shimadzu’s GC and GCMS solutions in the screening process to detect and mitigate the risks associated with EG and DEG contamination.
The pharmaceutical industry is dedicated to ensuring the patients’ safety, which requires the use of cutting-edge technology in quality control processes. Advanced analytical instruments are essential for achieving precision and reliability in quality control testing. In the following sections, we will highlight the importance of accurate screening and the pivotal role played by the Shimadzu’s GCMS in pharmaceutical quality assurance.
Importance of Accurate Screening of EG and DEG
Chemical contamination in pharmaceutical products can lead to fatal consequences. In Indonesia, for example, at least 195 deaths among children have been reported relating to ethylene glycol (EG) and diethylene glycol (DEG) contamination in medicinal syrup. In West Africa, Gambia, 70 child deaths were also suspected to be caused by contaminated medicinal syrup. This has caught the attention of the World Health Organization (WHO), hence leading to the issuance of a global alert on this issue.
Propylene glycol, glycerol, and sorbitol are commonly used in medicinal syrup as excipients. Their presence helps improve the solubility of the active ingredients during formulation. They also function as thickeners and sweeteners impacting the taste of the medication. These raw materials are easily contaminated with toxic ethylene glycol (EG) and diethylene glycol (DEG).
Over the past few decades, numerous contamination incidents of medicinal syrup with EG and DEG have been reported. Accidental ingestion of EG and DEG may result in abdominal pain, vomiting, diarrhoea, inability to pass urine, headache, altered mental state, and kidney injury which leads to death.

Analytical Instruments in Screening
In pharmaceutical quality control, the Shimadzu single quadrupole gas chromatograph-mass spectrometer, GCMS-QP2020 NX, emerges as a leading-edge instrument that offers fast and robust screening process for Ethylene Glycol (EG) and Diethylene Glycol (DEG).
The GCMS-QP2020 NX is an advanced screening analysis tool with high scan-speed capabilities. It features a Fast Automated Scan/SIM Type (FASST) mode that allows for consecutive collection of scan and single ion monitoring (SIM) data. With this powerful tool, it is possible to accurately identify and quantify both EG and DEG in medicinal syrup with just a single injection.

Introducing Brevis GC
This new space-saving GC delivers uncompromising analytical performance in a modern yet rugged design, easily meeting the analysis needs of laboratories in a range of industries.
Compact without Compromise
The compact Brevis GC-2050, with a 350 mm system width, including an auto-injector (AOC™-30i), makes even more use of lab space. Compared to the flagship Nexis™ GC-2030, the system's width has been reduced by approximately 35 %. At the same time, it is possible to connect additional headspace samplers, a mass spectrometer, and other accessories (available soon), providing the scalability to cover the analytical needs of today's GC/GCMS users.
Built-in Analytical Intelligence
Its intelligent features include:
- Automatic remote operation
- Automating the Procedures of Experienced Analysts, Clean Pilot
- Analysis Starts Immediately under the Optimal Conditions, Automatic Start and Stop Function
- Protecting Columns
- Supply Gas Check
Best-in-Class Performance
The Brevis GC-2050 provides best-in-class analytical precision. The latest auto-injector, AOC-30i, enables continuous analysis with a high level of precision that cannot be achieved with manual operation. In addition, the flow controller (AFC) with a built-in CPU supports constant linear velocity, constant flow rate, and constant pressure control of carrier gas to achieve outstanding analytical reproducibility with ultra-high speed and ultra-precise control.
Conclusion
It is extremely crucial to screen for Ethylene Glycol (EG) and Diethylene Glycol (DEG) in medicinal syrups, as their accidental presence can pose serious health risks. With Shimadzu's end-to-end solutions, you can quickly and effectively implement analytical testing to ensure good quality control.
