Status, terms of delivery and payment

Verification of devices

The second-hand devices are verified by Labexchange Service GmbH before delivery. You are receiving only fully functional devices.

Dispatch time

The stated dispatch times are the shortest possible ones for each article. The effective dispatch times can vary. The effective dispatch times will be stated in the order confirmation.

As a matter of principle, we are offering collective deliveries. The shipping time is calculated based on the position with the longest lead time. A partial delivery is possible on explicit request.

Shipping methods

Parcel services, forwarding agencies, self-pickup, delivery by Labexchange fleet.

Delivery information

Prices exclude shipping costs. Stated shipping costs are to be expected. Deviations are possible. If transport costs are not specified, please ask separately for them.

The stated transport and packing charges apply to the most favorable route if transport and are to be understood as subject to verification due to unexpected cost increases. By reason of unpredictable events, cargo rates and delivery times can change at any time and therefore have to be adapted to the recent situation. Import formalities and possible customs charges will be borne by the purchaser. Incoterm coding according to Incoterms 2010: For persons who collect the devices themselves: EXW, for dipatch by sea: CFR, by air freight: CPT, other shipments: DAP. Note for international shipments: A proof of preference/EUR1 will not be issued by us. When self-collecting/ordering EXW from countries within or outside the European Union, 16% VAT will be retained as a deposit until we have received the corresponding confirmation of arrival/bill of delivery from the buyer.

Terms of payment

We do not accept payment by letter of credit, PayPal, etc. In each case the invoice amount is payable without deduction. Discount is not granted.

Overview

The ED40 Electrochemical Detector measures current resulting from the application of potential (voltage) across electrodes in flowthrough cells. Depending an the method by which the potential is applied and the current measured, several different properties of the flowing solution can be determined. These measurements help answer the major questions analytical chemists ask: What's in it, and how muck is there?

Of course, other detectors are used in high performance liquid chromatography (HPLC). The UV-visible absorbance detector dominates all other forms of detection. Sensitivity is excellent for mang analytes, especially aromatic species, and transparent mobile phases are readily available. However, there are numerous analytes that haue very poor absorbance and are not detected with sufficient sensitivity by UV absorbance. Most of these nonchromophoric molecules are aliphatic organic molecules and inorganic ions. Low wavelength UV detection can be used, but at a loss in selectivity. Refractive Index detection can also be used. However, maintaining a stable baseline can be difficult, and RI detection is less sensitive and substantially less selective than UV detection.

Fortunately, a wide variety of nonchromophoric molecules can be detected with good or excellent sensitivity by one of several forms of electrochemical detection. These molecules include carboxylic, sulfonic and phosphonic acids; alcohols, glycols, aldehydes, and carbohydrates, primary, secondary, tertiary, and quaternary amines; sulfates, sulfoxides, thiols, sulfides, and mercaptans; and inorganic anions and cations. In addition, when compared to UV absorbance detection, electrochemical detection provides substantial improvements in sensitivity and selectivity for amine and hydroxy-substituted aromatics such as catecholamines.

The ED40 Electrochemical Detector is housed in a single-unit DX 500 enclosure (sec Figure 2-1). The detector is designed to be stacked an top of other DX 500 units, up to a maximum height of four units. Figure B-1 in Appendix B illustrates the recommended stacking configuration for DX 500 systems.
