Description

The C402CS7 is a JGS3 IR-grade infrared cuvette with 40mm path length and two-way light optical configuration — two opposing faces are polished to optical grade for standard absorbance measurements. With a 14ml internal volume (40 × 10 × 43 mm chamber), the cell is compatible with most commercial FTIR, NIR, and IR spectrophotometers. Manufactured from JGS3 fused silica with an extended transmittance window of 260–3500 nm — well beyond the 2500 nm cutoff of standard JGS1 quartz. Fabricated using Standard 80 (>80% transmittance) — precision-glued quartz panels for reliable optical alignment. The friction-fit PTFE cap serves as a dust cover that keeps particulates out of the sample during measurements.

Infrared Spectroscopy Applications

◆ FTIR Absorption Spectroscopy — functional-group identification, molecular fingerprinting, and quantitative analysis in the mid-IR

◆ NIR Spectroscopy — overtone and combination-band analysis for moisture, protein, fat, and carbohydrate determination

◆ Pharmaceutical QC — API identification, polymorph screening, and dissolution testing in the NIR/mid-IR range

◆ Petrochemical Analysis — hydrocarbon characterization, fuel-quality monitoring, and lubricant degradation studies

◆ Food & Beverage — sugar, alcohol, moisture, and adulterant detection via NIR/mid-IR absorption

◆ Polymer & Materials Science — functional-group mapping, curing-kinetics monitoring, and degradation analysis

◆ Environmental Monitoring — dissolved organic carbon, oil-in-water, and greenhouse-gas measurements

◆ Biological & Biomedical — tissue characterization, protein secondary-structure analysis, and biofluid screening

Why Two-Way Light?

Two-way light cuvettes have two opposing faces polished to optical grade, providing a single well-defined beam path for standard absorbance measurements. This is the standard configuration for FTIR, NIR, and UV-Vis-NIR spectrophotometers, delivering clean baseline performance and maximum signal-to-noise ratio for quantitative infrared analysis.

Why a PTFE Cap?

The friction-fit PTFE cap serves as a dust cover that keeps particulates and contaminants out of the sample during measurements. PTFE is chemically inert and will not leach absorbing compounds into the sample. While not airtight, the cap reduces evaporation during short measurement cycles and protects the optical surfaces when the cuvette is stored.

Why Standard 80?

Standard 80 uses precision-applied optical adhesive to bond JGS3 IR quartz panels, delivering >80% transmittance across the 260–3500 nm range. The glued construction provides excellent optical alignment at an economical price point. Best suited for aqueous and non-aggressive sample matrices; avoid prolonged contact with strong organic solvents, concentrated acids, or bases that may attack the adhesive layer.

Why JGS3 IR Quartz?

JGS3 is an infrared-grade fused silica with transmittance extending to 3500 nm — significantly beyond the ~2500 nm cutoff of standard JGS1 quartz. This extended window covers the critical O–H, C–H, and N–H overtone and combination bands in the NIR region as well as fundamental absorption bands in the mid-IR. JGS3 is the material of choice for FTIR liquid cells, NIR quantitative analysis, and any spectroscopic measurement where mid-infrared transparency is required.

Usage Tips

Rinse with a compatible solvent (e.g., ethanol or the measurement solvent) before first use to remove any residual particles.
Do not use abrasive materials or brushes on the polished optical faces — wipe gently with lens tissue.
Compatible with aqueous solutions only — avoid organic solvents, strong acids, and strong bases.
Store in the original protective case to prevent scratches on the optical windows.
For baseline correction, fill with your reference solvent and run a blank before sample measurements.
Compatible with Thermo Fisher, Bruker, PerkinElmer, Shimadzu, JASCO, Agilent, and most FTIR/NIR instruments.
