TOQUARTZ® Solving Application Challenges with Transparent Quartz Flow Cell with M5 Threaded Connectors

UV Absorbance Testing in Beverage Quality Control with Transparent Quartz Flow Cell with M5 Threaded Connectors

Beverage quality labs depend on UV absorbance testing to monitor color, clarity, and potential contaminants in flowing samples. The Transparent Quartz Flow Cell with M5 Threaded Connectors allows continuous inline measurement without interrupting production. A major challenge is obtaining stable absorbance values when sugars, acids, or carbon dioxide cause bubble formation and light scattering. Many plants also face inconsistent results when flow cells degrade under repeated cleaning cycles. TOQUARTZ® provides quartz construction with polished channels that maintain accuracy and durability across routine beverage quality checks.

Key Advantages

  • Polished channel Ra ≤ 10 nm
    — Low-scatter interior reduces baseline noise in CO₂-rich matrices at 430 nm.
  • Micro-path 0.2 mm option
    — Keeps absorbance within detector linear range (<1.5 AU) for dark beverages without dilution.
  • CIP durability pH 2–12, 60–80 °C
    — After 100 cleaning cycles, transmittance change ≤ 0.2% across 200–800 nm.
Find My Solution

TOQUARTZ® solution

A bottling line reported unstable UV baselines during inline color checks due to CO₂ bubbles and repeated hot-alkaline wash. After switching to the Transparent Quartz Flow Cell with M5 Threaded Connectors (0.2 mm path), baseline noise at 430 nm fell to ≤ 0.002 AU and color checks stayed <±1% variance over a 10-hour shift. Post-CIP optical drift measured ≤ 0.2% across 200–800 nm, eliminating mid-shift recalibration. Weekly unplanned stops for re-zeroing dropped from three to zero, stabilizing QA release times.

Trace Metal Analysis in Environmental Laboratories with Transparent Quartz Flow Cell with M5 Threaded Connectors

Environmental laboratories perform spectrophotometric tests to detect trace levels of heavy metals in water samples. The Transparent Quartz Flow Cell with M5 Threaded Connectors supports continuous flow analysis with high optical clarity, which is critical for low-concentration detection. The key challenge lies in avoiding contamination or signal interference from materials that leach ions into the sample stream. Conventional polymer-based cells often distort results when exposed to strong acids like nitric or sulfuric acid. TOQUARTZ® delivers inert, high-purity quartz channels that resist chemical attack and ensure reproducible, interference-free trace metal analysis.

Key Advantages

  • Acid-matrix compatible (2–5% HNO₃/H₂SO₄)
    — No visible attack at 25–60 °C during continuous flow testing.
  • Ultralow leaching (<1 ppb total alkali metals)
    — Quartz channel background below ICP-MS detection after 24 h acid soak.
  • Baseline drift ≤ 0.001 AU/60 min (220–240 nm)
    — Stable blanks for low-µg/L analyte detection.
Find My Solution

TOQUARTZ® solution

A river-monitoring lab saw blank drift ~0.006 AU at 230 nm using polymer cells in 2% HNO₃. With the Transparent Quartz Flow Cell with M5 Threaded Connectors, drift decreased to ≤ 0.001 AU over 60 min and total leachable Na/K/Ca remained <1 ppb. Spike-recoveries for Pb²⁺ at 10 µg/L improved from 89% to 98%, and replicate RSD at low levels dropped from 6.5% to 2.1%. Routine acid exposure no longer degraded the optical path, extending service intervals.

Optical Density Control in Algae Cultivation Systems with Transparent Quartz Flow Cell with M5 Threaded Connectors

Industrial algae cultivation requires real-time monitoring of cell density to optimize growth cycles and nutrient dosing. The Transparent Quartz Flow Cell with M5 Threaded Connectors provides continuous optical density measurements under high turbidity conditions. The challenge is maintaining reliable readings during rapid biomass accumulation and fluctuating temperatures in bioreactor systems. Many plastic or glass alternatives cloud over time, reducing accuracy and increasing replacement costs. TOQUARTZ® ensures transparent, thermally stable quartz flow cells with threaded connectors that withstand long-term integration in algae bioprocess monitoring.

Key Advantages

  • Extended OD range (600 nm)
    — Micro-path 0.2–1.0 mm maintains linearity up to OD₆₀₀ ≈ 4.0 without dilution.
  • Thermal cycling 20–80 °C × 500
    — No haze formation; ΔT (200–800 nm) ≤ 0.2% after cycling.
  • Fouling-resilient cleaning
    — Compatible with 0.5–1.0 M NaOH and 0.2% peracetic acid; transmittance deviation ≤ 0.3%.
Find My Solution

TOQUARTZ® solution

A 200 L photobioreactor ran daily OD₆₀₀ control but plastic flow cells clouded within two weeks, forcing frequent replacements. After adopting the Transparent Quartz Flow Cell with M5 Threaded Connectors (0.5 mm path), OD baseline drift fell from ~0.05 to ≤ 0.01, and calibration frequency moved from daily to weekly. Post-cleaning spectra stayed within ≤ 0.3% deviation, and replacement spend dropped by ~40% over a quarter. Continuous monitoring remained stable during rapid biomass ramps and temperature swings.
