XINSHENG is an HPLC system components manufacturer supplying individual modules for liquid chromatography equipment, preparative separation systems and OEM instrument projects. Our product range covers high-pressure infusion pumps, dynamic mixers, manual injection valves, UV and DAD detectors, fraction collectors and chromatography packing materials.
These HPLC components are available for customers assembling new chromatography instruments, sourcing individual replacement modules or expanding existing purification equipment. Instead of requiring a complete HPLC system, buyers can identify the components needed for solvent delivery, mixing, sample introduction, detection and fraction collection.
Each component performs a specific function within the chromatography process. Our product categories allow equipment manufacturers, laboratories and system integrators to select components according to their intended operating configuration.
| HPLC Component | Available Products | Function and Selection Focus |
|---|---|---|
| HPLC Pumps | 10, 50, 100, 200, 500, 1000 and 3000 mL/min nominal models | Mobile-phase delivery; select according to required flow, working pressure and solvent compatibility. |
| HPLC Mixers | Dynamic Mixer | Mixing solvent streams; evaluate mixing volume, system flow and gradient configuration. |
| HPLC Injection Components | 7725i Manual Injection Valve | Introducing samples into the mobile phase; check valve configuration, sample loop and pressure requirements. |
| HPLC Detectors | UV Detector and DAD Detector | Monitoring chromatographic peaks; evaluate wavelength requirements, flow cell and signal interface. |
| HPLC Fraction Collectors | 120 Fraction Collector and 3000 Fraction Collector | Collecting separated fractions; confirm vessel capacity, collection method and control requirements. |
| Chromatography Packing Materials | Chromatography packing media | Stationary-phase selection according to the separation method, column and sample characteristics. |
Preparative chromatography requires several modules to operate as a coordinated flow path. A typical configuration delivers mobile phase from the solvent supply through the pump and any required mixing device, introduces the sample through the injection module and passes it through the chromatography column. The detector monitors the separated compounds before the relevant fractions are collected.
The physical configuration depends on the elution method and the selected equipment. Mixing arrangements, detector flow paths and fraction collection control should be determined from the system requirements rather than assuming that every HPLC module can be connected directly.
Pump and Mixer: The mixing device must be suitable for the system flow, pressure and selected solvent delivery arrangement.
Injection Valve and Fluid Path: Sample loop volume, valve pressure rating, tubing dimensions and fitting types must be compatible with the chromatography method.
Column and Detector: The detector flow cell and connections should accommodate the intended flow without exceeding the pressure limits of the detection module.
Detector and Fraction Collector: The selected collection method must account for the available detector output, control signals and collection timing.
Control Equipment: Electrical signals, software control and communication interfaces must be checked for each module before system integration.
Component procurement depends on the equipment already available and the functions required. For an existing HPLC system, the primary concern is matching the replacement module to the current mechanical, fluidic and electrical interfaces. For a new instrument, components should be selected as part of a coordinated equipment configuration.
| Project Type | Typical Purchasing Requirement | Information Needed |
|---|---|---|
| New HPLC Equipment Assembly | Pumps, mixers, injection components, detectors and fraction collectors for a new system | Chromatography method, required flow, operating pressure, detector requirements and control architecture |
| Replacement of an Existing Component | A compatible module for an existing HPLC installation | Original model, technical specifications, installation dimensions and connection information |
| Extension of Equipment Functions | Additional detection, solvent mixing or fraction collection modules | Current system configuration, intended new function and available interfaces |
| OEM Chromatography Instrument Project | Multiple HPLC components for integration into a customer's equipment | Instrument design, operating specifications, control requirements and expected purchasing quantity |
Components used in chromatography equipment must be compatible with both the operating conditions and the surrounding modules. Mechanical fit alone does not guarantee that a replacement pump, detector or fraction collector will operate correctly with an existing chromatography system.
Confirm the required flow range, maximum working pressure, tubing size, connection type and wetted-material compatibility. Special attention should be given to high-pressure connections between the pump, injection valve and column.
Equipment requiring electronic control should be evaluated for its available input and output signals, power supply, communication interfaces and control functions. Where a module is intended for a third-party instrument, the existing controller specifications should be provided for compatibility assessment.
For systems that collect purified compounds, detector output and fraction collector operation must be coordinated. Buyers should identify whether fractions will be collected according to time, signal-based events or another supported control method, and verify the relevant functions of the selected equipment.
Instrument dimensions, tubing routing, ventilation, maintenance clearance and connection access should be considered when incorporating modules into benchtop instruments, laboratory installations or preparative equipment cabinets.
XINSHENG works with customers requiring individual chromatography modules and OEM/ODM equipment configurations. For instrument development projects, component requirements can be reviewed according to the intended chromatography process, system layout and operating specifications.
OEM component sourcing may involve standard modules or customer-specific requirements relating to mounting dimensions, fluid connections, electrical interfaces, equipment appearance and supporting technical documentation. The availability of requested modifications is determined during the technical review of the relevant product.
Component Requirements: Types and quantities of pumps, mixers, detectors, valves or fraction collectors.
Operating Specifications: Flow, pressure, solvent composition, injection requirements and detection method.
Equipment Interfaces: Tubing connections, mounting dimensions, electrical power and control signals.
Integration Scope: Individual component supply, multiple-module procurement or requirements related to a complete system.
Technical Documents: Required datasheets, installation information and available interface documentation.
Purchasing Information: Estimated order quantity, project schedule and destination market.
Customers who already have a chromatography instrument may only require a replacement detector, pump, injection valve or collection module. In these cases, purchasing an individual component can address the specific equipment requirement without replacing the complete system, provided compatibility is confirmed.
For customers developing a new separation process or requiring a coordinated combination of solvent delivery, injection, detection and fraction collection, a complete preparative HPLC system may provide a more suitable procurement route.
The wider liquid chromatography equipment portfolio also includes chromatography columns and related purification equipment for customers evaluating an overall system configuration.
XINSHENG lists UV and DAD detectors, dynamic mixers, manual injection valves and fraction collectors as individual products. Customers can submit the required component model and operating specifications for product selection and quotation.
Replacement suitability depends on the original system's fluid connections, pressure and flow requirements, electrical interfaces and control signals. Provide the existing equipment model and relevant technical documentation so that the proposed replacement can be evaluated. Compatibility should not be assumed solely from the component's function or appearance.
A UV detector measures absorbance at its supported wavelength settings. A diode array detector (DAD) uses a diode array to acquire spectral information across its specified wavelength range. Selection depends on the analytical method, wavelength requirements and the actual capabilities of the detector model.
Consider the expected fraction volume, number and type of collection vessels, system flow and collection control method. The detector signal and timing requirements should also be reviewed when the collector will operate as part of an automated preparative system.
Customers can submit a component list and instrument requirements for an OEM/ODM sourcing discussion. Relevant information includes the quantities, fluid path, operating conditions, mounting arrangement and control interfaces. Product specifications and customization requirements should be confirmed before an order is finalized.
