Infection, Respiratory, Allergy & Immune

Diagnostic testing for infectious, respiratory, allergic, and immune-mediated conditions. Useful for initial workup, treatment follow-up, and long-term disease surveillance.

Infection and Infestation drugs

Overview

Infection and infestation drugs encompass a wide variety of therapeutic agents designed to combat bacterial, viral, fungal, and parasitic pathogens. This group includes antibiotics, antivirals, antifungals, and antiparasitic compounds used in both systemic and topical treatments. Analytical testing for these drugs is critical to verify potency, purity, and stability, as subtherapeutic or contaminated products can contribute to antimicrobial resistance or treatment failure. Comprehensive analysis supports quality assurance in formulation development, manufacturing, and post-market surveillance.

Solutions

High-performance liquid chromatography (HPLC) and ultra-performance liquid chromatography (UPLC) are routinely employed to separate and quantify active pharmaceutical ingredients (APIs) and degradation products in anti-infective formulations. Coupling with mass spectrometry (LC-MS/MS) enhances specificity, enabling trace-level detection of complex metabolites and residual impurities. Gas chromatography (GC-FID or GC-MS) is used for volatile compounds and solvent residues, while UV-Vis spectrophotometry offers rapid screening and identity confirmation. Additional instruments such as dissolution testers, stability chambers, and microbial testing platforms help assess drug release, shelf-life, and sterility. Together, these analytical tools ensure infection and infestation drugs meet stringent quality, safety, and regulatory standards across the pharmaceutical lifecycle.

Respiratory system drugs

Overview

Respiratory system drugs include therapeutic agents designed to prevent, treat, or manage diseases affecting the lungs and airways—such as asthma, chronic obstructive pulmonary disease (COPD), pneumonia, and allergic conditions. These analytes typically encompass bronchodilators, corticosteroids, mucolytics, and antihistamines, often formulated as inhalants, tablets, or injectables. Because respiratory medications are highly dosage-sensitive and frequently combined in complex formulations, analytical testing plays a key role in ensuring consistent potency, purity, and stability. Reliable data on active ingredients and excipients helps safeguard both therapeutic efficacy and patient safety.

Solutions

High-performance liquid chromatography (HPLC) and ultra-performance liquid chromatography (UPLC) are the primary tools for separating and quantifying active compounds and degradation products in respiratory formulations. When coupled with mass spectrometry (LC-MS/MS), they enable precise profiling of corticosteroids, beta-agonists, and anticholinergics in both raw materials and finished products. Gas chromatography (GC-FID or GC-MS) is used for volatile analytes, such as propellants and residual solvents in inhalation products. UV-Vis spectrophotometry supports rapid screening and potency checks, while dissolution testers and stability chambers evaluate drug release and environmental performance. Together, these instruments provide the analytical foundation needed to verify quality, consistency, and regulatory compliance in respiratory drug development and manufacturing.

Allergic disorder drugs

Overview

High-performance liquid chromatography (HPLC) and ultra-performance liquid chromatography (UPLC) are widely used to separate and quantify antihistamines, corticosteroids, and other active compounds within complex formulations. Coupling with mass spectrometry (LC-MS/MS) provides high sensitivity for trace-level detection and impurity profiling in both raw materials and finished products. Gas chromatography (GC-FID or GC-MS) supports the analysis of volatile substances and residual solvents, while UV-Vis spectrophotometry offers rapid potency checks. Supporting instruments such as dissolution testers, stability chambers, and Karl Fischer titrators help evaluate formulation consistency, moisture control, and shelf-life. Together, these analytical platforms ensure allergic disorder drugs deliver reliable efficacy, quality, and safety throughout their development and production cycle.

Solutions

Gas Chromatography (GC) equipped with multiple detectors—such as Thermal Conductivity Detector (TCD), Argon Ionization Detector (AID), Electron Capture Detector (ECD), and Photoionization Detector (PID)—provides a comprehensive analytical approach for process vent sampling. Each detector offers unique advantages: TCD for general-purpose detection of inorganic and permanent gases; AID and PID for sensitive detection of organic vapors and hydrocarbons; and ECD for selective measurement of halogenated and electronegative compounds. Samples are typically collected using gas sampling bags, canisters, or direct injection systems to preserve composition. Modern GC systems with multi-detector configurations, precise flow and temperature control, and automated data acquisition allow simultaneous or sequential analysis of complex gas mixtures. This integrated approach ensures accurate, sensitive, and reproducible monitoring of process vent emissions across a broad range of compounds and concentration levels.

Immune system drugs

Overview

Immune system drugs include a diverse range of compounds designed to modulate or support immune function, such as immunosuppressants, immunostimulants, monoclonal antibodies, and cytokine modulators. These analytes are used in the management of autoimmune diseases, organ transplantation, inflammatory disorders, and immune deficiencies. Because immune-targeting drugs often have complex molecular structures and narrow therapeutic indices, rigorous analytical testing is critical to ensure potency, purity, and biological activity. Quality control throughout formulation and production helps maintain consistent therapeutic outcomes and regulatory compliance.

Solutions

High-performance liquid chromatography (HPLC) and ultra-performance liquid chromatography (UPLC) are essential for separating and quantifying small-molecule immunosuppressants such as cyclosporine and tacrolimus. For larger biological drugs—like monoclonal antibodies or recombinant proteins—liquid chromatography coupled with mass spectrometry (LC-MS/MS) or size-exclusion chromatography (SEC) provides detailed molecular characterization, including purity and aggregation profiling. Capillary electrophoresis (CE) supports charge variant and peptide mapping analyses, while UV-Vis spectrophotometry assists in concentration verification. Supporting instruments such as stability chambers and dissolution testers help evaluate formulation robustness and long-term stability. Together, these analytical platforms ensure immune system drugs meet strict standards for safety, efficacy, and batch-to-batch consistency.
