Tetraethylene Glycol (TEG, also known as TTEG) is a colorless, low-odor, hygroscopic and viscous liquid with the molecular formula C₈H₁₈O₄. It features low volatility, excellent thermal stability and high solubility, being fully miscible with water, ethanol, acetone and most organic solvents. With low toxicity and good chemical compatibility, TEG is a versatile industrial raw material widely used in natural gas processing, solvents, chemical intermediates and other fields.

The primary application of TEG is natural gas dehydration and gas drying. As a highly efficient desiccant, it selectively absorbs water vapor from natural gas, pipeline gas and industrial gases, reducing moisture content to meet pipeline transportation and industrial use standards. Its high boiling point and low vapor pressure make it ideal for continuous dehydration processes, ensuring stable performance and low loss during regeneration.
In the solvent industry, TEG serves as a high-boiling specialty solvent. It is used in aromatic hydrocarbon extraction to separate benzene, toluene and xylene from petroleum fractions, and as a solvent for printing inks, coatings and cleaning agents, providing slow evaporation and excellent dissolving power for resins and organic compounds. It also acts as a cosolvent in cosmetics and personal care products to improve formulation stability.
As a chemical intermediate, TEG participates in esterification and polycondensation reactions to produce plasticizers, polyester resins and polyurethane materials. It enhances the flexibility and durability of polymer products, and is also used in the production of lubricant additives, brake fluids and heat transfer fluids, offering good low-temperature performance and thermal stability.
Additionally, TEG is applied in hydraulic fluids, textile auxiliaries and gas purification processes, demonstrating its broad adaptability and value across multiple industrial sectors.

Product Description

Tetraethylene Glycol is a colorless, viscous liquid with low volatility and excellent thermal stability. It is a polyether diol featuring high purity (≥99.0%), good solubility with water, alcohols, and many organic solvents, and low toxicity. 

Our TEG is packaged in 200L steel drums for industrial bulk supply and sealed HDPE containers (5L, 20L) for laboratory or small-scale needs, ensuring safe storage and transportation with its anti-leakage and corrosion-resistant packaging.

 It is characterized by its high boiling point, low freezing point, and superior lubricating properties, making it adaptable to various demanding industrial environments.

In terms of usage and applications, Tetraethylene Glycol is widely used as a heat transfer fluid in high-temperature heating systems due to its excellent thermal stability. In the petrochemical industry, 

it serves as a solvent and dewaxing agent for lubricating oils and fuels. It is also an important raw material in the production of polyesters, polyurethanes, and plasticizers, contributing to the manufacturing of coatings, adhesives, 

and elastomers. Additionally, TEG finds application in the textile industry as a softener and in the pharmaceutical sector as an excipient. Its multifunctional properties and reliability make it a crucial component in numerous industrial and

 manufacturing processes.

Plak een reeks herhaalde metingen (CSV of één getal per regel). De calculator berekent het gemiddelde, de standaardafwijking en 95% CI, en detecteert uitschieters (Grubbs + Dixon Q).

Scheidingsteken: komma, spatie, tab, nieuwe regel. Minimaal 3 metingen.
📐 Statistische formules
  • x̄ = Σxᵢ / n — rekenkundig gemiddelde
  • s² = Σ(xᵢ - x̄)² / (n-1) — steekproefvariantie
  • s = √s² — standaardafwijking
  • RSD% = (s / x̄) × 100% — relatieve standaardafwijking
  • CI₉₅ = x̄ ± t(0.05, n-1) × s / √n — Student's t
  • G = |xᵢ - x̄| / s — Grubbs-test
  • Q = |xsuspect - xnearest| / |xmax - xmin| — Dixon Q-test

Why Acetonitrile vs Methanol?
PropertyAcetonitrile (ACN)Methanol (MeOH)
Viscosity (20°C)0.37 cP0.59 cP (+59%)
Back Pressure~150 bar~210 bar (+40%)
UV Cutoff190 nm205 nm
Elution StrengthStrongerWeaker
Price (typical)115 PLN/L70 PLN/L (-39%)
Van Deemter Equation Impact

H = A + B/u + Cu

Higher viscosity (MeOH) → lower optimal flow rate → longer runtime.

Buffer Selection: Why NH₄HCO₃?
  • Volatile: MS-compatible (evaporates without residue)
  • pH range: 6.5–8.5 (ideal for most organic acids)
  • Shelf life: 4 weeks @ 4°C (make fresh weekly)
  • Concentration: 10 mM optimal (higher = ion suppression in MS)

Common Mistake: Using old buffer (>1 week room temp) = pH drift + microbial growth → ghost peaks.

Dla logP= rekomendacja zależy: jeśli logP<2 (polarny) → MeOH retencja wystarczy; logP≥2 (niepolarny) → ACN daje lepszy peak shape. Dla tej molekuły (MW=194.23, CAS 112-60-7) zaczynaj od ACN w gradiencie 5→95% B.

Gradient Problem From The Lab

Rt shift between days (±0.3 min)

Every morning the first 5 injections have Rt 8.2 min. Then 8.5 min. Then 8.2 again the next day. Why?

Our Gradient Strategy

  • Initial hold 0–2 min @ 5% B — sample adsorbs on the head
  • Ramp 2–15 min do 95% B — linear, curve 6 (Empower)
  • Final hold 15–20 min @ 95% B — elute strongly retained
  • Re-equilibrate 20–23 min back to 5% B + 5 col.volumes

Log k = log kw − S·φ, gdzie φ = fraction B. Optymalny gradient: Δφ ≈ 0.6–0.8 per 5 t0. Dla kolumny 250×4.6mm @ 1 mL/min → t0 ≈ 2 min → gradient 10–12 min.

Prep Mistakes That Ruined The Run

Pressure too high — what next?

Pressure rises to 400 bar (max 300 for this column). The system is blaring an alarm. Do you shut the pump down? Yes/no?

Sample Prep Protocol

  1. Dissolve 10 mg of sample in 10 mL of mobile phase (initial composition)
  2. Sonikuj 5 min → vortex 30 s
  3. Filtruj 0.22 μm PTFE (nie PVDF — adsorbuje!)
  4. Transfer 1 mL do HPLC vial z septum PTFE/silikon
  5. Przechowuj 4°C max 48h

Why Filter 0.22 μm?

Particles >0.22 μm clog the column inlet frit. Pressure rises +50 bar per 100 injections. Column lifetime drops from 2000 to 500 injections. Filter cost: 2 PLN. Column cost: 1800 PLN.

Incorrect integration — publication rejected

Kasia M., PhD Analytical Chemistry, UJ 2025-06-03 Poziom 4/5
Wat er gebeurde:

Submission to JPBA. Reviewer 2: „Peak at 12.4 min shows manual integration, but baseline slope suggests co-elution". I had to revalidate the whole method. 3 months of delay.

💡 Lekcja:

Manual integration = a red flag for reviewers. Solve CO-ELUTION in methods dev, not in integration. Optimise the gradient instead of force-fitting the peak.

Peak tailing ruined my results

Anna K., PhD student, Warszawa 2024-03 Poziom 3/5
Wat er gebeurde:

I ran the method exactly as written. Main peak Tf = 2.8 (should be <1.5). Integration impossible. I repeated it 6× — always tailing.

💡 Lekcja:

Causes: (1) buffer pH 8.2 instead of 7.0, (2) 2-month-old buffer (bacteria!), (3) C8 column instead of C18. Fix: fresh buffer pH 7.0 + switch to C18 → Tf 1.2, Rs 1.9→2.3.
